Discuss the experimental demonstration of the formation of beats. How can we find the unknown frequency of a fork (i) by loading with wax (ii) by filing fork ?

Explain how the phenomenon of beats may be used for finding the unknown frequency of a tuning fork.

If the prong of a tuning fork is filed, its frequency………………and if it loaded with wax, its frequency……………………

Two tuning forks when sounded together produced 4beats//sec . The frequency of one fork is 256. The number of beats heard increases when the fork of frequency 256 is loaded with wax. The frequency of the other fork is

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

When two tuning forks were sounded together , 20 beats were produced in 10 seconds. On loading one of the fork with wax, the number of beats increases. If the frequency of unloaded fork is 512Hz , calculate the frequency of other.

Two tuning forks A and B give 4 beats/s when sounded together. If the fork B is loaded with wax 6 beats/s are heard. If the frequency of fork A is 320 Hz, then the natural frequency of the tuning fork B will be

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

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

Four beats are produced on vibrating an unknown tuning fork with another fork of frequency 252 Hz. On loading the unknown fork with little wax and vibrating with another fork 2 beats/s are produced. The frequency of unknown fork before loaded will be
