## These are the “S” in WSQ. You must have them under your video notes completed by the due date on the Unit Plan.

Part 1: Mechanical Waves and Its Parts

1. What does a wave carry/

2. Describe a medium.

3. What are the crowded parts of the wave called?

4. How do you measure wavelength?

Part 2: Math of Waves

Use the following picture to answer the questions below:

1. How many full wavelengths are there in the picture?

2. Calculate its' frequency. Assume 1 sec.

3. What would the frequency of the wave be if this wave came out in 2 secs?

Use the following picture to answer the questions below:

4. How many full wavelengths are there in the picture?

5. If this picture was taken over one second, what is its' frequency?
