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

Question

A string fixed at both ends whose fundamental frequency is 240 Hz is vibrated with the help of tuning fork having frequency 480 Hz, then (A) string will vibrate with a frequency of 240 Hz (B) string will vibrate in resonance with the tuning fork (C) string will vibrate with a frequency of 480 Hz, but is not in resonance with the tuning fork (D) string is in resonance with tuning fork, and hence vibrates with a frequency of 240 Hz

If one of the natural frequencies of the string matches with the source frequency then resonance condition will arise and string will vibrate with the source frequency.

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

string will vibrate with a frequency of 240 Hz

string will vibrate in resonance with the tuning fork

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

string is in resonance with tuning fork, and hence vibrates with a frequency of 240 Hz

If one of the natural frequencies of the string matches with the source frequency then resonance condition will arise and string will vibrate with the source frequency.
