A string fixed at both ends oscillates in 5 segments,
length 10 m and velocity of wave is 20 `ms^(-1)`. What is
the frequency?

A

5 Hz

B

15 Hz

C

10 Hz

D

2 Hz

Text Solution

Verified by Experts

The correct Answer is:
a
Frequency of vibration is given by
`v=p/(2l)sqrt(T/m) ("where," v=sqrt(T/m))`
`therefore v= p/(2l)v=(5xx20)/(2xx10)=5` Hz
