A skipper on a boar notices wave crests passing his anchor chain every 5 s. He estimates the distance between wave crests to be 15 m. He also correctly estimates the speed of the waves. Show that this speed is 3 m/s.

Step 1of 3 The skipper notices that 15 meters of wave pass each 5 seconds, or equivalently, that 3 meters pass each 1 second, 1 Frequency of wave= Hz5 Wavelength of the wave =15 m so the speed of the wave must be Speed = 3 m/s Step 2 of 3 We have relation v=f Where, v is speed of wave f is frequency of wave is wavelength of wave
