A vibrating sonometer wire in resonance ...

A vibrating sonometer wire in resonance with a tuning fork of frequency 150 Hz. If only loop is formed on the wire and the length of one loop is 40 cm, then the velocity of transverse waves on the wire will be

A

a. `120 m//s`

B

b. `240 m//s`

C

c. `90 m//s`

D

d. `60m//s`

Text Solution

Verified by Experts

The correct Answer is:
A

`lambda/2 = L :. lambda = 2 xx 40 = 80` cm
` :. V = n lambda = 150 xx 0.8 = 120` m/s
