Three sound waves of equal amplitudes have frequencies `(v -1), v, (v +1)`. They superpose to give beats. The number of beats produced per second will be

Three sound waves of equal amplitudes have frequencies (n-1) ,n (n+1) .They superimpose to give beats.The number of beats produced per second will be

Three sound sources A , B and C have frequencies 400 , 401 and 402 H_(Z) , respectively. Cacluated the number of beats noted per second.

Three sound sources p,q and r have frequencies 400 Hz, 401 Hz and 402 Hz respectively. Calculate the number of beats nodes per second.

if three sources of sound of equal intensities and having frequencies 300 Hz , 301 Hz and 302 Hz are sounded together, the number of beats heard is

Two waves of frequencies 6 Hz and 10 hz are superposed. The beat frequency produced is

Beats are produced by two waves y_(1) = a sin 2000 pi t and y_(2) = a sin 2008 pi t The number of beats heard per second is

Two open pipes of length L are vibrated simultaneously. If length of one of the pipes is reduced by y. then the number of beats heats per second will be if the velocity of sound is v and y lt lt L :-

Two waves of same amplitude a and frequency v and having a phase difference of pi//2 radian, are superposed. The amplitude of resultant wave is

Two sound waves of equal intensity l, generates beats. The intensity of sound l_(s) produced in beats will be

A tuning fork produces 4 beats per second when sounded togetehr with a fork of frequency 364 Hz. When the first fork is loaded with a little wax ten the number of beats becomes two per second. What is the frequency of the first fork?
