A string fixed at both ends whose fundamental frequency is `240 Hz` is vibrated with the help of a tuning fork having frequency `480 Hz`, then

A

The string will vibrate with a frequency of `240 Hz`

B

The string will vibrate in resonance with the tuning fork

C

The string will vibrate in resonance with a frequency of `480 Hz`, but is not a resonance with the tuning fork

D

The string is in resonance with the tuning fork and hence vibrate with a frequency of `240 Hz`

Text Solution

Verified by Experts

The correct Answer is:
B
If one of the natural frequencies of the string matches with the source frequency , then resonance condition will arise and the string will vibrate with source frequency .
