The velocity of transverse wave in a str...

The velocity of transverse wave in a stretched string is proportional to

A

T

B

m

C

`T^2`

D

`m^(-1//2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`v prop (1)/(sqrtm)`
`n_1l_1 = n_2l_2`
`therefore l_2= (n_1l_1)/(n_2) = (240xx60)/(360) = 40`
`l_1-l_2 = 60-40 = 20cm`
