The velocity of waves in a string fixed ...

The velocity of waves in a string fixed at both ends is 2 m / s . The string forms standing waves with nodes 5.0 cm apart. The frequency of vibration of the string in Hz is

A

40

B

30

C

20

D

10

Text Solution

Verified by Experts

The correct Answer is:
C
Since, `(lambda)/(2)=5cmimplieslambda=10cm`
`f=(v)/(lambda)=(200)/(10)=20Hz`.
