An observer standing at the sea coast observes `54 waves` reaching the coast per minute. If the wavelength of a wave is `10 m`, find the wave velocity.

A

54 m/s

B

9 m/s

C

10 m/s

D

6 m/s

Text Solution

Verified by Experts

The correct Answer is:
B
`n = (54)/(60)` rps
`:. v= n lamda = (54)/(60) xx 10 = 9 m//s`
