A sonometer wire , `100 cm` in length has fundamental frequency of `330 Hz`. The velocity of propagation of tranverse waves along the wire is

Options

A. `330 m//s`
B. `660 m//s`
C. `115 m//s`
D. `990 m//s`

Answer

B

Explanation

For fundamental mode
`(lambda//2) = 100 cm or lambda = 200 cm`
As `n = 330 Hz`, hence
`V = n lambda = 330 xx (200)/(100) = 660 m//s`
