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

20 Hz

B

5 Hz

C

10 Hz

D

15 Hz

Text Solution

Verified by Experts

The correct Answer is:
B
Given that `(5lamda)/(2)=Limplies(5lamda)/(2)=10`
`thereforelamda=4m`
Using `v=vlamda`
`implies(20)/(4)=v`
`thereforev=5Hz`
