(a) Does the change in frequency due to Doppler effect depend on the distance between source (b)Does the change in frequency due to Doppler effect on the fact that source is moving towards the observer or observer is moving towards the source ?

A source of sound moves towards an observer

For point source, the wavefront is

A source of sound moves towards an observe.

The frequency of a source of sound as measured by an observer when the source is moving towards him with a speed of 30 m/s is 720 Hz. The apparent frequency when the source is moving away after crossing the observer is x xx 10^2 Hz what is the value of x. ......... (velocity of sound is 330 m/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

A source is moving towards an observer with a speed of 20 m / s and having frequency of 240 Hz . The observer is now moving towards the source with a speed of 20 m / s . Apparent frequency heard by observer, if velocity of sound is 340 m / s , is

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

A source emitting a sound of frequency f is placed at a large distance from an observer. The source starts moving towards the observer with a uniform acceleration a. Find the frequency heard by the observer corresponding to the wave emitted just after the source starts. The speed of sound in the medium is v.
