An observer standing near the sea shore observes 54waves/min. If the wavelength of the water wave is 10 m then the velocity of water wave is :

A

` 540 ms^(-1)`

B

` 5.4 ms ^(-1)`

C

` 0.184 ms ^(-1)`

D

` 9 ms ^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
Freequency ,n = `(54)/(60)`
` rArr " " n= (9)/(10)`
` therefore , v= n lambda `
` = (9)/(10) xx 10 = 9m//s`
