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`.

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 ).

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 . .

A tuning fork vibrats with frequnecy 256 Hz and gives one beat per seond with the third normal mode of vibration of an open pipe. What is the length of the pipe (Speed of sound in air is 340 ms^(-1) )
