Please Help ASAP Imagine you are sitting on a surfboard in the ocean, waiting to catch a big wave. When the ocean is still, you are sitting at a point that would be the midpoint (the undisturbed position) of any waves that come your way. You look out to see and see a set of waves coming your way. What you see is actually a pattern of troughs followed by crests of the waves moving toward you and the shore. The distance between the crests is 5 meters. A crest passes you every 20 seconds.
a. Calculate the wavelength.
b. Calculate the frequency.
c. Calculate the wave velocity.
