A student is on a sail boat in the ocean. The boat is moving up and down but not moving horizontally. She counts that the boat rises and falls 39 times in 60s. She also estimates the distance between crests of the waves as shown. Answer each of the following questions based on her estimations. What is the wavelength of the ocean waves? m What is the period of the boat's oscillations? 4m in What is the frequency of the boat's oscillations? Hz At what speed are the ocean waves moving? m/s 0000
