A string of length 2 m is fixed at both ...

A string of length 2 m is fixed at both ends. If this string vibrates in its fourth normal mode with a frequency of 500 Hz then the waves wouldf travel on it is with a velocity of

A

250 m/s

B

500 m/s

C

750 m/s

D

125 m/s

Text Solution

Verified by Experts

The correct Answer is:
B
There are four loops
` :. 4 ( lambda/2) = 200`
` :. lambda = 1 m " and " V = nlambda = 500 ` m/s
