Two persons `A` and `B` ,each carrying a source of sound of frequency `nu` ,are standing a few meters a part in quiet field. A starts moving to words B with a speed u. If V is the speed of sound,the number of beats heard per second by A will be

Two persons A and B , each carring a source of frequency 300 H_(Z) , are standing a few metre apart. A starts moving towards B with velocity 30 m//s . If speed of sound is 300 m//s , which of the following is true?

On a quiet day, two persons A and B, each sounding a note of frequency 580 Hz, are standing a few metres apart. Calculate the number of beats heard by each in one second when A moves towards B with a velocity of 4 ms^(-1) . (Speed of sound in air = 330 ms^(-1) .)

A source of sound of frequency n is moving towards a stationary observer with a speed S. If the speed of sound in air is V and the frequency heard by the observer is n_(1) ,the value of n_(1)//n is

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) ).

A band playing music at a frequency f_(0) is moving towareds a wall at a speed v_(0) . A motorist is following the band with a speed v_(m) . If v be the speed of the sound the expression for beat frequency heard by motorist is

A source of sound S of frequency 500 Hz situated between a stationary observer O and wall W , moves towards the wall with a speed of 2m//s . If the velocity of sound is 332m//s . Then the number of beats per second heard by the observer is (approximately)

A band playing music at a frequency f is moving towards a wall at a speed v_(b) . A motorist is following the band with a speed v_(m) . If the speed of sound, obtain an expression for the beat frequency heard by the motorist.
