[" A certain number of "],[" beats are heard "],[" when two tuning "],[" forks of natural "],[" frequencies "n_(1)" and "n_(2)],[" are sounded "],[" together.The number "],[" of beats when one of "],[" the forks is loaded "]

Two tones of frequencies n_(1) "and" n_(2) are sounded together. The beats can be heard distinctly when

Three tuning forks of frequencies 248 Hz, 250 Hz, 252 Hz, are sounded together.The beat frequency is,

20.Two tuning forks have frequencies 200Hz and x.When they are sounded together 4 beats/ sec are heard.The value of x is

The natural frequency of a tuning fork P is 432 Hz. 3 beats/s are produced when tuning fork P and another tuning fork Q are sounded together. If P is loaded with wax, the number of beats increases to 5 beats/s. The frequency of Q is

Two tuning forks when sounded together produce one beat per 0.4 s. Then the difference of their frequencies 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

A tuning fork when sounded with tuning fork of frequency 256 produces 4 beats//sec and when sounded with another of frequency 250 produces 2 beats//sec . The frequency of the 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.
