Wave problems
This type of wave is like a sound wave.
What type is it?
Calculate the period of the wave
Calculate the wavelength of one wave
If the wave height is 4 meters, what is
the amplitude?
You are watching waves
come in to the shore ready
to go in. You see a wave
train come in and 5 waves
come in over 60 seconds.
a. Calculate the period of the wave.
b. Calculate the frequency.
c. You estimate the wavelength to be 10 meters.
What is the wave’s velocity?
