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____________.

A fork of unknown frequency when sounded with one of frequency 288 Hz gives 4 beats per second and when loaded with a piece of wax again gives 4 beats per second. How do you account for this and what was the unknow frequency ?

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

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

A tuning fork 'P' of frequency 280Hz produces 6 beats/s with unknown tuning fork 'Q'

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

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 unknown frequency gives 4beats with a tuning fork of frequency 310 Hz. It gives the same number of beats on filing. Find the unknown frequency.

If a tuning fork of frequency 512Hz is sounded with a vibrating string of frequency 505.5Hz the beats produced per sec will be
