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?
