while watching ocean waves at the dock of the bay. otis notices that 10 waves pass beneath him in 30 seconds. he also notices that the crests of succesive waves exactly coincide with the posts that are 5 meters apart. what are the period frequency wavelength and speed of the ocean waves?
wavelength = 5 meters, given
period time/waves = 30 seconds/10 waves = 3 seconds
frequency = 1/period = 1/3 Hertz
speed = distance/time = 5/3 m/s
