A sonometer wire of certain length is stretched under a tension of 5 kgf and vibrates in unison with a tuning fork of unknown frequency. When the tension is changed to 4 kgf, it produces 5 beats per second with the tuning fork. Determine the frequency of tuning fork.

Two tuning forks A and B produce 4 beats//s when sounded together . A resonates to 32.4 cm of stretched wire and B is in resonance with 32 cm of the same wire . Determine the frequencies of the two tuning forks .

50 tunning forks are arranged in increasing order of their frequencies such that each gives 4 beats/sec with its previous tuning fork. If the frequency of the last fork is octave of the first, then the frequency of the first tuning fork is

When a little wax is put on the prongs of a tuning fork, then the frequency of vibration of a tuning fork will

A number of tuning forks are arranged in the order of increasing frequencies and any two successive tuning forks produce 4 beats/second, when sounded together. If the frequency of the last tuning fork is the octave of the first tuning fork and if the frequency of the first tuning fork is 256 Hz, then the number of tuning forks is

The prongs of the tuning fork are filed, then the frequency of the tuning fork after filing will be

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 :-
