Two tuning forks A and B are vibrating at the same frequency 256 Hz. A listener is standing midway between the forks. If both tuning forks move to the right with a velocity of `5(m)/(s)`, find the number of beats heard per second by the listerner (speed of sound in air is `330(m)/(s)`).

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 ).

Figure shows a person standing somewhere in between two identical tunning forks, each vibrating at 512 Hz. If both the tuning forks move towards right at a speed of 5.5 ms^-1 , find the number of beats heard by the listener. Speed of sound in air =330 ms^-1 .

If a vibrating tuning fork of frequency 255Hz is approaching with a velocity 4m//s perpendicular to a wall. The number of beats produced per sec is (speed of sound in air =340m//s )

A tuning fork of frequency 380 Hz is moving towards a wall with a velocity of 4(m)/(s) Then the number of beats heard by a stationary listener between direct and reflected sound will be (velocity of sound in air is 340(m)/(s) )

Two identical tuning forks vibrating at the same frequency 256 Hz are kept fixed at some distance apart. A listener runs between the forks at a speed of 3.0 m s^-1 so that he approaches one tuning-fork and recedes from the other. find the beat frequency bserved by the listener. Speed of sound in air = 332 m s^-1 . .
