Wave problems
1. This type of wave is like a sound
wave.
What type is it?
2. Calculate the period of the wave
3. Calculate the wavelength of one
wave
4. If the wave height is 4 meters, what
is the amplitude?
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?
