Question

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`

Answer 1

Correct Answer - 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 .
