1. Physics Review: 7 Questions

2. Directions Split your group of 4 into pairs
Every pair needs a white board
On the top of your board, write

3. How the game works
For every question we ask, you have to decide how much to risk from Once you have used that number, you cannot use it again.

4. Question A: Calculation
You see something happen 12 times in 30 seconds. What is the magnitude of the frequency? What is the magnitude of the period?

5. Question B
A ray of light starts in ethyl alcohol, goes through glass, and ends up air. 1) Draw a diagram that shows the wave’s path. 2) At each new medium, label list whether it is going faster or slower.

6. Question C
Can 2 waves have the same frequency but different amplitudes? Explain
How do you know a wave has a “high” frequency?

7. Question D
The substance in white “n2” is glass. Predict what the n1 substance is. Explain how you know.

8. Question E: Superposition
You see 2 sets of waves (A and B). Predict which wave will produce the loudest sound. Label each wave using terms from class.

9. Question F What type of wave is this?
How many “complete” waves do you see?
What do you call the area with a lot of dots?
What do you call the area with hardly any dots?

10. Question G: Calculation
A signal is sent with a wave speed of 83,000 m/s. If the frequency of this wave is 7.2 x 107 hz, what is the period?
What is the magnitude of the wavelength?
