Suppose you stand in the water a meter or two from one end of a swimming pool. a. You push down hard once on a large beach ball floating on the water in front of you. What do you observe? b. Now you push ball a few tines (do not too many tines). Does the speed at which of waves move away from you depend on how frequently you push the ball up down? Explain. c. Draw a top view of the wave-crest pattern that you would see in the water at one instant of time. How does the distance between adjacent crests differ if you bob the ball up and down more frequently or less frequently?
