The maximum number of beats that can be heard per second is

A person with vibrating tuning fork of frequency 338Hz is moving towards a vertical wall with a speed of 2 ms^(-1) . Velocity of sound in air is 340 ms^(-1) . The number of beats heard by that person per second is

A person with vibrating tuning fork of frequency 338 Hz is moving towards a vertical wall with speed of 2 ms^(-1) Velocity of sound in air is 340 ms^(-1) The number of beats heard per second is

If vibrating tuning fork of frequency 255Hz is moving with a velocity 4ms^-1 towards the wall the number of beats heard per second is (speed of sound in air = 340ms^-1 ).

Two sound sources emitting sound each of wavelength lambda are fixed at a given distance apart. A listener moves with a velocity u along the line joining the two suorces. The number of beats heard by him per second is

Two sound sources emitting sound each of wavelength lambda are fixed at a given distance apart. A listener moves with a velocity u along the line joining the two sources. The number of beats heard by him per second is

There are three sources of sound of equal intensity with frequencies 400, 401 and 402 vib/sec . The number of beats heard per second is

Beats are produced by two waves given by y_1 = a sin2000 pit and y_2 =asin2008 pit . The number of beats heard per second is
