Waves e-test
Begin by opening the word document found here or on the resource gallery entitled "M5 physics - waves e-test. Save a copy with a new filename: "your name - waves e-test". (You will submit this file via this website at the end (theoretically) or on the resource gallery if the internet is not cooperating.)
Use this file to record your answers to the questions. Always include appropriate units when necessary.

1. Use the animation below to answer all parts of this question. The animation can be played (or paused) by pressing the button on the bottom left corner. It can be restarted by pressing the button in the upper right corner.
a) What is the wavelength of the wave pictured?
b) What is the period of the wave shown? Describe how you obtain your answer.
c) Calculate the frequency of the wave shown.
d) Calculate the velocity of the wave shown.
e) Estimate the amplitude of the wave shown. Describe how you did this. (What does amplitude mean?)
2. Use the animation below to answer all parts of the question. Time can be adjusted by sliding the dot along the time slider. The animation can be reset by pressing the button on the top right corner.
b) What is the period of the wave shown? Describe how you obtain your answer.
c) Calculate the frequency of the wave shown.
d) Calculate the velocity of the wave shown.

2. Use the animation below to answer all parts of the question. Time can be adjusted by sliding the dot along the time slider. The animation can be reset by pressing the button on the top right corner.
a) Find the time it takes for one cycle of the pendulum.
b) Find the average time for one cycle of the pendulum by first finding the time for 5 cycles and then finding the average per cycle.
c) Do your answers for a) and b) match? Explain why they might be different and which one you think is more accurate to use for period.
d) Consider the simple pendulum above. You are asked to investigate the effect of changing one aspect of this pendulum. Write a research question and then list your independent variable, dependent variable, and control variables.
3. Use the animation below to answer all parts of the question. Wavelengths and amplitudes can be adjusted using the sliders along the right hand side. The animation can be played and stopped using the buttons on the bottom right, and can be progressed frame by frame by using the "step animation" button.
The red and blue waves represent 2 different waves, while the purple wave represents the resultant wave you would see if the blue and red waves were to pass through the same medium.
a) Adjust the red and blue waves so that they create a standing wave (the purple wave). State the adjustments required for this.
b) Take a screenshot of your wave at a point that demonstrates total destructive interference. Explain why this occurs. (Remember you can use the step animation button to make it move bit by bit.)
c) By using screenshot(s), label at least one node and at least one antinode on your standing wave. Explain what is happening at each location.
When you have finished, carefully save your file in your own documents and submit it using the form below. If (and only if) the internet is not cooperating, save it on the resource gallery in the same folder in which you found it with the filename "your name - waves e-test".
