A boat moving with a velocity of 20 ms¹ in a sea, is rocked by waves. If the waves are 80 m apart, after how much time the boat will bounce up? |

Answer» concept: The distance between the two consecutive crests in transverse wave motion is called wavelength. The boat bounces up, i.e., it travels from crest to the consecutive crest along wave motion. Wavelength = distance between two consecutive crests i.e., λ=80m Velocity of wave = 20 m/s Hence, time in one bounce of boat t=λ/v=80/20=4s |
