Two sources `S_1` and `S_2` of same frequency `f` emits sound. The sources are moving as shown with speed `u` each. A stationary observer hears that sound. The beat frequency is (`v=`velocity sound)

A sound source is moving towards a stationary observer with 1/10 of the speed of sound. The ratio of apparent to real frequency is

What should be the velocity of a sound source moving towards a stationary observer so that apparent frequency is double the actual frequency (Velocity of sound is v )

If a source of frequency n moving with velocity v crosses a stationary observer, then the change in the frequency of sound heard by the observer will be (velocity of sound = V)

A source of frequency n is moving with a uniform velocity v towards a stationary observer. If the velocity of sound is V, then the change in frequency would be -

Two sources of sound S_(1) and S_(2) produce sound waves of same frequency 660 Hz . A listener is moving from source S_(1) towards S_(2) with a constant speed u m//s and he hears 10 beats/s. The velocity of sound is 330 m//s . Then, u equals :

Two sources of sound moving with same speed v and emitting frequency of 1400 Hz are moving such that one source s_1 is moving towards the observer and s_2 is moving away from observer. If observer hears beat frequency of 2 Hz. Then find the speed of source. Given v_(sound) gt gt v_(source) and v_(sound) = 350m/s

Two sources of sound moving with same speed v and emitting frequency of 1400 Hz are moving such that one source s_1 is moving towards the observer and s_2 is moving away from observer. If observer hears beat frequency of 2 Hz. Then find the speed of source. Given v_(sound) gt gt v_(source) and v_(sound) = 350m/s

Two source of sound S1 and S2 produce sound waves of same frequency 660 Hz. A listener is moving from source S1 towards S2 with a constant speed um/s and he hears 10 beat/s. Then, u is equal to ________ (in m/s).
