Observer A is at rest. Source `S_(1)` is moving towards observer A and source `S_(2)` is moving away from observer A. velocity of sound is `330(m)/(sec)`. `beta`= beat frequency heard per second by A. Approximate value of `beta` is:

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s . The speed of sound is 330 m/s . the frequency heard by the observer will be

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s . The speed of sound is 330 m/s . the frequency heard by the observer will be

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

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s.The speed of the sound id 330 m/s.The frequency heard by the observer is

A source is moving towards a stationary observer, so that the apparent frequency increases by 50%. If velocity of sound is 330 m/s, then velocity of source is

A source of frequency 1 kHz is moving towards a stationary observer with velocity of 0.9 times that of sound. What is the frequency heard by the observer ?
