When a tuning fork A of unknown frequency is sounded with another tuning fork B of frequency 256Hz, then 3 beats per second are observed. After that A is loaded with wax and sounded, the again 3 beats per second are observed. The frequency of the tuning fork A is

A tuning fork of unknown frequency when sounded with another tuning fork of frequency 256 Hz produces 4 beats per second, and on loading with a little amount of wax, it again produces 4 beats per second. The unknown frequency is____________.

When a tuning fork of frequency 341 is sounded with another tuning fork, six beats per second are heard. When the second tuning fork is loaded with wax and sounded with the first fork, the number of beats is two per second. The natural frequency of the second tuning fork is

When a tuning fork of frequency 341 is sounded with another tuning fork, six beats per second are heard. When the second tuning fork is loaded with wax and sounded with the first fork, the number of beats is two per second. The natural frequency of the second tuning fork is

On sounding fork A with another tuning fork B of frequency 384 Hz , 6 beats are produced per second .After loading the prongs of A with wax and then sounding it again with B , 4 beats are produced per second. What is the frequency of the tuning fork A .

On sounding fork A with another tuning fork B of frequency 384 Hz , 6 beats are produced per second .After loading the prongs of A with wax and then sounding it again with B , 4 beats are produced per second. What is the frequency of the tuning fork A .

Tuning fork A when sounded with a tuning for B of frequency 480 Hz gives 5 beats per second. When the prongs of A are loaded with wax, it gives 3 beats per second. The original frequency of A is

Tuning fork A when sounded with a tuning for B of frequency 480 Hz gives 5 beats per second. When the prongs of A are loaded with wax, it gives 3 beats per second. The original frequency of A is

When tuning forks A and B are sounded together 5 beats per second are heard. Frequency of A is 250Hz . On loading A with wax 2 beats per second are produced with B. The frequency of B is

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 of unknown frequency produces 4 beats per second when sounded with another tuning fork of frequency 254 Hz. It gives the same number of beats per second when unknown tuning fork loaded with wax . The unknown frequency before loading with wax is
