Wave Properties & Phenomena

The three most common types of waves that we encounter in our daily life are water, sound, and light waves. While water and sound waves can only travel through a medium, light waves don’t need one. In this activity, you’ll study the similarities and differences among water, sound, and light waves.

To begin your activity, open this simulation: Wave Interference.

There are three tabs, Water, Sound, and Light. Observe these waves and then draw conclusions from your observations.

Question 1

Water: Start with the Water tab. Note that light areas represent places where the water is high (crests). Dark areas represent low points (troughs).

The water drops should already be dripping from the faucet. You can increase their frequency by using the Frequency slider. You can expand or decrease the size of your “sink space” by clicking the green +/- sign in the upper right corner of the sink. Using the controls on the far right, you can add measuring tools, add a wall, add another faucet, or insert a single-slit or two-slit barrier.

Part A

What kind of wave patterns do you observe in the sink in the top view?

15pxSpace used(includes formatting): 0 / 30000

Part B

Click on the Show Graph button at the bottom of the window. (If you have expanded your sink, you’ll probably need to decrease its size again to see this graph.) The graph shows the moving water level, which is the actual amplitude of the waves.

What general mathematical graph function does this look like? What pattern do you observe in the amplitude of these waves? Provide a hypothesis to explain this pattern in the amplitude.

15pxSpace used(includes formatting): 0 / 30000

Part C

What happens when you increase the frequency of the water drops? What happens to the wavelength of the waves on the surface of water?

15pxSpace used(includes formatting): 0 / 30000

Part D

If you increase the frequency, what happens to the velocity of the wave?

In answering this question, describe how you determined the velocity as well as the result you arrived at. Then, provide a scientific explanation for this result, based on your knowledge of waves.

Part E

What happens when you add a second drip and space both the drips close together? Describe the pattern they form and explain the cause for this pattern in detail.

15pxSpace used(includes formatting): 0 / 30000

Part F

Turn off the second drip and then add a barrier with one slit. What do you observe on the right side of the wall? What do you observe on the left side of the wall? From a physics perspective, explain your observations of what is happening on both sides of the barrier.

Question 2

Sound: Now click the Sound tab.

Part A

On the Sound tab, investigate briefly all the phenomena you explored with water waves above and describe any similarities in your results for sound. Specifically, describe

wave pattern as seen on the screen
shape and amplitude of the graph
effect of frequency on wavelength
effect of frequency on velocity
pattern with two sources
wave pattern with a single-slit barrier

Electricity, Fields & DNA

By Academic Wizard Blog

Electricity, Fields & DNA

discussion- An enormous amount of electricity is created at power-generating stations and sent across the country through wires that carry high voltages. Appliances, power lines, airport and military radars, substations, transformers, computers, and other equipment that carries or uses electricity all generate electromagnetic fields.

Many questions have been raised about how electromagnetic fields affect our bodies. Do they pose a public health risk? Perform an Internet search to find information about the effects of electromagnetic fields on public health. Then, discuss the pros and cons of using equipment that produces an electromagnetic field.

Here is one authoritative source to get you started: electromagnetic fields and public health.

Double Helix Structure of DNA

This task connects the physics of electrostatics with molecular biology. Molecular biology is the study of the structure and function of the cell at the molecular level. DNA’s double helix structure consists of two strands held together by electrostatic forces. Do online research on electrostatics and molecular biology, and then answer the following questions. Here are two sources to start with:

Part A

What is DNA and what is its role in life? List DNA’s four nucleotide bases.

Electric Field of Dreams

In this activity, you will explore the relationship between the strength and direction of the electric field lines to the type of charge on a particle and its magnitude. You will also explore the interactions between two or more charged particles and observe their movement. To begin your activity, open the simulation: Electric Field of Dreams. ‪‪Electric field of dreams‬ 1.0.0-dev.10‬

Directions:
At any time you may

click the Reset All button to reset all the settings;
click the Play/Pause button to pause or resume the motion; or
pause the motion and then click the Step button to observe the motion step-by-step.

Part A

To begin, click the Add button to add one object to the system. Observe the electric field around this charged object. You may move the object around the field by dragging it with your cursor. While the arrows indicate the direction of the electric field around the charge, the length of the arrows indicates the field strength. Based on your observations of the field, what is the charge on this object? Give your reasoning.

15pxSpace used(includes formatting): 0 / 30000

Part B

Set the charged object in motion by dragging it and releasing it. What do you observe about the behavior of the field lines in the vicinity of the object?

15pxSpace used(includes formatting): 0 / 30000

Part C

Add another charged object to the electric field by clicking the Add button again. What is the charge of this new object? Give your reasoning. What do you observe about the behavior of both the objects as well as the field lines in the vicinity of both the objects?

Electric Field Hockey ‪‪Electric field hockey‬ 1.0.0-dev.10‬

In this activity, you will again explore the relationship between an electric field and charged particles in the field, but this time you’ll have a gaming challenge. To begin, open Electric Field Hockey.

Directions:
On the control bar, make sure that the Puck is Positive and the Field boxes are checked. Also, make sure that the Practice option is selected.

Your aim is to score goals by manipulating the black puck (test charge) into the blue-colored bracket (goal) on the right. Think smart and place positive source charges (red) and negative source charges (blue) in such a way that the black puck moves into the goal.

Note that when you place a red, positive source charge in the hockey field, a red arrow appears on the black puck (test charge) showing the force the positive charge exerts on the puck. Similarly, when you place a blue, negative source charge in the hockey field, a blue arrow appears on the black puck (test charge) showing the force the negative charge exerts on the puck.

Part A

Place a red charge in the hockey field and click Start. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?

15pxSpace used(includes formatting): 0 / 30000

Part B

Click Reset and then click Clear. Now, place a blue charge in the hockey field and click Start. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?

15pxSpace used(includes formatting): 0 / 30000

Part C

Manipulate the mass of the puck by dragging the Mass bar to the right for increasing the mass and to the left for decreasing it. What changes do you see in the speed of the puck? Which principle works behind this change?

15pxSpace used(includes formatting): 0 / 30000

Part D

In the same situation, what do you observe about the relationship between the speed of the black puck and its distance from the blue charge?

15pxSpace used(includes formatting): 0 / 30000

Part E

You can make the puck travel in complex ways by placing a set of charges around on the field. So, here’s your game challenge: Arrange source charges around to propel the puck from its starting position into the goal. That’s pretty easy for a straight shot; you just put a negative charge behind the goal. But what if there are barriers in the way? That’s a real test of your physics understanding, including Newton’s laws of motion and electrostatic forces. Game’s on!

On the control bar, check the Trace, Field, and Anti-alias boxes. The game has three Difficulty levels. Start with Difficulty level one and arrange source charges to get the puck into the goal. Once you’ve made a score at any level, increase the Difficulty level. Take a screen capture of two of your most difficult goals and paste them here. At least one of these should be at Difficulty level 2 or 3.

(Note: On a Windows computer, you can use the key combination Alt-Print Screen to copy the currently-active window to your clipboard. When you capture an image of this simulation window, paste the image into an image-processing program such as Paint, and save the image as a file. Then use the Insert Image button to insert the file into the response area.)

Home Electricity Use & Conservation

By Academic Wizard Blog

Home Electricity Use & Conservation

Discussion- It’s possible to save a great deal of electrical energy (and money and natural resources) with some simple changes in household electrical use. The trouble is that most of these changes mean either changing behavior or spending money. Do an Internet search and review a few ways to save electrical energy. Discuss at least one change that you think would be reasonable and worthwhile to do in your own home in the next year. Provide your rationale.

Home Energy Use

In this activity, you are going to perform an experiment to track the amount of power you and your family use, then look at some basic patterns in that usage. (NOTE: If you live in an apartment or home in which you do not have access to the electrical meter, consult with your instructor about alternative arrangements, like teaming with a classmate to gather this data.)

This experiment is going to span the course of a full week and require 12 meter readings. It really involves two separate experiments:

tracking daily energy use for a week to compare any usage variations from day to day
comparing a single high-usage time period of a few hours with a single low-usage time period of a few hours to help you identify the extremes in your household electrical use

You can easily do both experiments during the same time period. This approach would be the easiest and fastest way to proceed. Read the instructions for both Part A and Part B if you wish to do both experiments at the same time.

To begin, you’ll need to find your electric meter, which could be inside or outside of your home. Many electric meters these days are digital and pretty easy to read, but if you have an older “dial-type” meter, go to this electric meter reading guide to learn about how to read and understand it.

For each of the two experiments below, you will first record three simple pieces of data in a table:

1) day and date, 2) time, and 3) the kWh reading from the meter.

Then record the results of three simple calculations:

kWh used: Calculate kWh used since the last reading (subtraction).
Hours elapsed: Calculate the number of hours since the last reading (subtraction rounded to a whole number).
Average kW used: (kWh used)/(hours elapsed). If this number turns out to be 0.36, for example, it means that your average household power usage for the time period was about 360 watts, the equivalent of running six 60-watt bulbs for that whole time period.

Part A

Daily Electrical Usage: Data Collection

Pick a convenient time of day to take readings from your electric meter. You’ll need readings roughly a day apart, but if they differ by only an hour or two, that should be fine. Pick a consistent time you’ll remember, though, such as after getting home for the day. You need to start by doing an initial meter reading, then follow up with a reading every day for the next 7 days. You’ll do 8 readings in all.

Record your readings in the tables below. In addition to the data fields described above, there is a lot of room for usage notes. Record anything that might have substantially affected the electrical usage since your previous reading. This might include the amount of time people were around and awake at home, use of specific devices such as an air conditioner, clothes dryer, TV, or lighting.

Part B

Usage Extremes: Data Collection

For this experiment, you’ll measure electrical usage during a time period when you expect to have very light electrical usage (for instance, while you’re asleep at night or during the day when no one is at home). Likewise you’ll measure electrical usage during a time period when you expect to have heavier than average electrical usage. This time period might be in the evening, when lights and other appliances are on. Both of these time periods should be at least 4 hours long, to increase the accuracy of your results.

Record your results in the tables below for each situation. For each time period, you’ll need to take an initial and a final reading.

Type your response here:

Part C

Let’s start the analysis by looking at your “extreme usage” cases. Compare the two cases in detail—low usage period versus high usage period. Discuss differences between the two as well as any surprises. Things you should cover in your discussion: How much difference was there in average power usage (avg. kW) between the low-usage and high-usage time periods? What might have been running during the low-usage period that used energy? Identify likely “stealth” energy users that you could not turn off during the low-usage period. What do you suppose contributed most to the usage during the high-usage period?

15pxSpace used(includes formatting): 0 / 30000

Part D

Having looked at your “extreme usage” cases, analyze your day-to-day usage. Discuss in detail. Specifically, compare higher usage days to lower usage days. Were there significant variations? Do your conclusions regarding the “extreme” cases help to explain any daily variations? What were the surprises or new insights you had in reviewing this day-to-day usage record?

15pxSpace used(includes formatting): 0 / 30000

Part E

It is possible to save a great deal of electrical energy (and money and natural resources) with some simple changes. You’re probably familiar with what some of those changes are and are now more attuned to your own electrical usage. The trouble is, most of these changes either mean changing behavior or spending money. Search the Web for a few ways to save electrical energy. Record them below and categorize them, if possible, as “change behavior” or “spend money.” You might want to consider adding a “neither” category. There are a few things that don’t really require much change or money at all. Include your sources in your answer.

15pxSpace used(includes formatting): 0 / 30000

Which times of the year are best for seeing the northern lights, and where are the best places to view them? Explain your answers. Also identify links to good images. If you’ve ever seen the aurora borealis, describe your experience and note the time and place that you saw it.

Faraday’s Law

Electric generators use the properties of electromagnetism to transform kinetic energy into electrical energy. Many electric generators work by spinning a permanent magnet near coils of wire. Experiment with this simulation of electricity generation to visualize how this process works. Once the simulation opens, try moving the permanent magnet around to see what happens. Also rapidly switch the polarity of the magnet by repeatedly clicking on the magnet icon at the bottom of the page, and observe the effect.

Part A

Try moving the magnet in the different ways described in the table below,. Record your observations in the second column of the table.

Motion Observations

Move the magnet straight through the coil, leading with the north pole. Once the magnet is completely through, move it back to its original position.

Move the magnet straight through the coil, only this time leading with the south pole. Once the magnet is completely through, move it back to its original position

Put the magnet in the center of the coil, but don’t move it.

Put the magnet on the outside of the coil. Repeatedly move it up and down while outside of the coil.

Keeping the magnet outside of the coil. Repeatedly move it back and forth horizontally.

Place the magnet back inside of the coil. Now repeatedly switch the polarity of the magnet by pressing the button toward the bottom-right of the page over and over again.

Nuclear Reactions & Energy

Nuclear Reactions & Energy

Scientists such as Heinrich Hertz, Philipp Lenard, Max Planck, and Albert Einstein made scientific contributions that ultimately demonstrated that light is electromagnetic radiation, and that it has a “dual nature.” Some electromagnetic phenomena are best explained with a particle model, and some with a wave model. In a sense, “wave” and “particle” are just easy mental models for light. We employ them because we are used to seeing waves and particles—such as those in water waves and baseballs—in our daily lives. Electromagnetic radiation is a basic concept in physics, but it doesn’t fit completely into one of these neat little boxes.

Research and discuss at least one modern technology that employs electromagnetic radiation and that can be explained by the wave model, the particle model, or a combination of the two. Some possible technologies include solar panels, burglar alarms, cameras, and cell phones.

Psychotherapy for Addictive Disorders

By Academic Wizard Blog

Psychotherapy for Addictive Disorders

Addictive disorders can be particularly challenging for clients. Not only do these disorders typically interfere with a client’s ability to function in daily life, but they also often manifest as negative and sometimes criminal behaviors. Sometime clients with addictive disorders also suffer from other mental health issues, creating even greater struggles for them to overcome. In your role, you have the opportunity to help clients address their addictions and improve outcomes for both the clients and their families.

Resources

Be sure to review the Learning Resources before completing this activity. Click the weekly resources link to access the resources.

Physics and Justice Topics

Power Point that explains the physics of a rainbow. What is a rainbow? What will affect if you see a rainbow or two? What do dispersion, refraction, and reflection have to do with rainbows?

Technical violations of parole, such as failing to inform a parole officer about a change in residence, contribute significantly to prison overcrowding. Evaluate the effectiveness of returning parolees to prison for technical violations. Should there be more leniency in handling these cases, or is strict enforcement necessary to maintain public safety and the integrity of the parole system? Discuss the benefits and problems associated with strict enforcement of technical violations, considering the potential impact on recidivism rates, prison overcrowding, and the successful reintegration of parolees into society. Be sure to include examples from the textbook in your answer.

Victims of violence by intimate partners and family. In your opinion, what are the key issues with this topic?

(Rituals of Strain, IPV, and Familicide) Our argument is that structural factors are often overlooked. After addressing that question, watch the video below. What is your opinion of this “tool” some police departments started using over a decade ago to ID domestic violence victims at greatest risk? What seem to be the advantages? What about disadvantages?

Comprehensive General Answers

1️⃣ The Physics of a Rainbow
A rainbow is a meteorological and optical phenomenon caused by the interaction of sunlight with water droplets in the atmosphere. It occurs when sunlight enters a raindrop, slows down, bends (refracts), reflects off the inside surface of the droplet, and then exits, bending again as it leaves. This process separates white sunlight into its component colors — red, orange, yellow, green, blue, indigo, and violet — creating a circular arc of color in the sky. Whether one sees a single or double rainbow depends on how many internal reflections occur inside the water droplets. A primary rainbow results from one reflection, while a secondary rainbow, fainter and reversed in color order, forms from two reflections. The principles of dispersion (light splitting into colors), refraction (bending of light as it enters a new medium), and reflection (light bouncing inside the droplet) all combine to create the beautiful arcs we recognize as rainbows.

2️⃣ Technical Violations of Parole
Technical violations of parole, such as failing to report a change of address or missing a meeting with a parole officer, contribute heavily to prison overcrowding. Returning parolees to prison for these minor infractions is often ineffective, as it does little to rehabilitate individuals or reduce recidivism rates. According to Siegel (2018), strict enforcement may ensure accountability and protect public safety but can also lead to unnecessary incarceration of individuals who pose minimal risk. A more balanced approach would involve alternative sanctions, such as community service, counseling, or electronic monitoring. Leniency, when applied carefully, allows parolees to reintegrate successfully while conserving correctional resources. Strict enforcement may maintain the integrity of the parole system, but excessive punishment for minor violations undermines rehabilitation goals and strains the prison system.

Comprehensive General Answers (use/modify for your submission)

1) Introduction (≈180 words)

This experiment investigates the relationship between [identify independent variable] and [identify dependent variable] to test how changes in one affect the other under controlled conditions. The theoretical basis is that [state the relevant law or principle — e.g., Newton’s second law, Hooke’s law, conservation of energy, Ohm’s law, diffusion kinetics, etc.], which predicts that when [independent variable] changes, [dependent variable] will [increase/decrease/behave in X way] according to a mathematical relationship. For example, if studying a spring-mass system, Hooke’s law (F = −k x) and the equation for simple harmonic motion (T = 2π√(m/k)) relate force, displacement, mass, spring constant, and period. In the procedure we measure [dependent variable] at several controlled levels of [independent variable], keeping other factors constant (temperature, friction, initial conditions) to isolate the effect. Data will be analyzed using graphical methods (best-fit line or curve), calculation of percent error versus theoretical predictions, and discussion of sources of experimental uncertainty. The experiment tests whether observed behavior matches theoretical expectation and provides practice in measurement, data analysis, and error estimation. (If you used outside sources for theory, cite them in your lab report references.)

Salary Negotiation & Ethics

By Academic Wizard Blog

Salary Negotiation & Ethics

Jake is interviewing for a marketing coordinator position at TechCorp, a growing software company. He is currently earning $38,000 at his small nonprofit job but knows that similar positions at tech companies typically pay between $55,000 and $65,000. During the interview, everything is going well until the hiring manager, Ms. Chen, asks:

“So, Jake, what’s your current salary?”

Jake hesitates, realizing he’s in a tough spot. He knows that if he tells the truth about his current $38,000 salary, TechCorp might offer him something like $42,000-$45,000, thinking that he will be happy with an offer of a higher wage than he currently makes. The position should pay closer to $60,000, based on market rates and the actual earnings of other marketing coordinators at TechCorp. However, he does not want to lie during the interview process.

Jake knows that his nonprofit salary does not match his skills or market value, and he is concerned that revealing it could lead to a lowball offer and hurt his long-term earning potential.

Two bills were submitted to Congress in March 2025 that would amend the Fair Labor Standards Act (FLSA) of 1938. H.R. 2007 would require employers to disclose the pay range of a position to applicants. H.R. 2219 would prohibit hiring companies to ask an applicant what their current salary and benefits are.

Please discuss the following with your peers:

In your opinion, what should Jake do in this situation?
Is it fair and ethical for employers to base new salary offers on previous wages? Why or why not?
How might this practice perpetuate pay inequalities across different industries or demographics?
