The couple of tuning forks produces 2 beats in the time interval of 0.4 seconds. So the beat frequency is

31 tuning forks are arranged in series in increasing order of frequencies and the frequency of the last tuning fork is 3 times the frequency of the first. If each tuning fork produces 4 beats/second with the preceding one, the frequency of the last tuning fork is

A tuning fork vibrates with 2 beats in 0.04 second. The frequency of the fork is

A tuning fork of frequency 100 when sounded together with another tuning fork of unknown frequency produces 2 beats per second. On loading the tuning fork whose frequency is not known and sounded together with a tuning fork of frequency 100 produces one beat, then the frequency of the other tuning fork is

A tuning fork of frequency 100 when sounded together with another tuning fork of unknown frequency produces 2 beats per second. On loading the tuning fork whose frequency is not known and sounded together with a tuning fork of frequency 100 produces one beat, then the frequency of the other tuning fork is

Two tuning forks, one of frequency 340 Hz and second of some unknown frequency produces 5 beats. When filling is done to second fork, then they produces 2 beats. Find initial frequency of second tuning fork.

A tuning fork of frequency 100 when sounded together with another tuning fork of unknown frequency produces 2 beats per sec . On loading the second tuning fork , sounded together with first tuning fork , produces one beat , then the frequency of the second tuning fork is

Two tuning forks having frequency 256 Hz (A) and 262 Hz (B) tuning fork. A produces some beats per second with unknown tuning fork, same unknown tuning fork produce double beats per second from B tuning fork then the frequency of unknown tuning fork is :-

Two tuning forks having frequency 256 Hz (A) and 262 Hz (B) tuning fork. A produces some beats per second with unknown tuning fork, same unknown tuning fork produce double beats per second from B tuning fork then the frequency of unknown tuning fork is :-

Two tuning forks having frequency 256 Hz (A) and 262 Hz (B) tuning fork. A produces some beats per second with unknown tuning fork, same unknown tuning fork produce double beats per second from B tuning fork then the frequency of unknown tuning fork is :-
