4. 1. This type of wave is like a sound wave. What type is it?

5. 2. Calculate the period of the wave

6. 3. Calculate the wavelength of one wave

7. 4. If the wave height is 4 meters, what is the amplitude?

8. You are watching waves come in to the shore ready to go in. Click on the video linked to image at right, or use the following data You see a wave train come in and 5 waves come in over 60 seconds. You estimate the wavelength to be 10 meters. 5. Calculate the period of the wave. 6. Calculate the frequency. 7. What is the wave’s velocity?
