Stationary waves are produced in 10 m long stretched string. If the string vibrates in 5 segments and wave velocity 20 m/s then the frequency is :-

A

2 Hz

B

4 Hz

C

5 Hz

D

10 Hz

Text Solution

Verified by Experts

The correct Answer is:
C
`n =5`
`f_(5) = (nv)/(2l) = (5 xx20)/(2xx10) = 5 ` Hz.
