A boat anchor is rocked by waves whose consecutive crests are `100 m` apart. If the wave speed of the moving crests is `20 m//s`, calculate the frequency at which the boat rocks.

Text Solution

Verified by Experts

Given `lambda = 100` m.

`v = 20"m s"^(-1)`
Now ` v= v lambda`
`therefore v = (v)/(lambda) = (20)/(100) = 0.2` Hz
