A tuning fork gives 15 beats per second when sounded with a sonometer wire of length 200 cm and 20 beats per second with that of length of 250 cm. calculate the frequency of the fork.

A tuning fork produces 10 beats per second with sonometer wire of length 95 cm and 100 cm . Find the frequency of the fork .

In an experiment, it was found that a tuning fork and sonometer wire gave 5 beats per second, both when the length of wire was 1m and 1.05m. Calculate the frequency of the fork.

A fork of unknown frequency gives 4 beats per second when sounded with another of frequency 256 . The fork is now loaded with a piece of wax and again 4 beats per second are heard. Calculate the frequency of the unknown fork.

A tuning fork when vibrating along with a sonometer produces 6 beats per second when the length of the wire is either 20 cm or 21 cm . Find the frequency of the tuning fork.

Two tuning forks when sounded together produce 4 beats per second. The first produces 8 beats per second. Calculate the frequency of the other.

A length of 34 cm of a sonometer wire gives 5 beats per second with a tuning fork.It again gives 5 beats per second when the length of the wire is increased to35 cm. What is the frequency of fork?

A tuning fork produces 2 beats per second when sounded with another tuning fork of frequency 250 Hz. It gives the same number of beats per second when loaded with wax. The initial frequency of 1^(st) tuning fork is

A tuning fork produces 2 beats per second when sounded with another tuning fork of frequency 250 Hz. It gives the same number of beats per second when loaded with wax. The initial frequency of 1^(st) tuning fork is

A tuning fork gives 4 beats with 50 cm length of a sonometer wire. If the length of the wire is shortened by 1 cm, the number of beats is still the same. The frequency of the fork is
