A boat at unchore by waves whose crests are `100m` apart and velocity is `25 m//s` The hour bounces up once in every

Options

A. `2500 s`
B. `75 s`
C. `4s`
D. `0.25 s`

Answer

c

Explanation

The distance between the two constant crests is transverse wave motion is called wavelength .The boat hounces up ,i.e. it travels crest in the consercative crest wave motion
Wavelength = between two consecutive crest ltvbrgt i.e. `lambda = 100 m`
`velocity of wave = 25 m//s`
Hence , time in one hence of boat
` t = (lambda)/(v) = (100)/(25) = 4s`
