Question

a boat at anchor is rocked by waves whose consecutive crests are 0.1km apart, the wave velocity of the moving crest is 72 km h . what i sthe frequency of the rocking boat​

Answer 1

Step-by-step explanation:

The distance between the two consecutive crests in transverse wave motion is called wavelength.

The boat bounces up, ie, it travels from crest to the consecutive crest along wave motion.

Wavelength =distance between two consecutive crests

ie,

Velocity of wave =2m/s

Hence, time in one bounce of boat
