A : In Doppler's effect the value of apparent frequency depends on the relative motion between source and observer .
R : The change in frequency in Doppler effect is independent from the distance between source and observer .

The change in frequency due to Doppler effect does not depend on

A : Doppler's effect in sound is asymmetric but in light , it is symmetric R : In Sound , change in frequency depends on the individual velocity of both the source as well as the observer . In light , change in frequency depends on the relative velocity between source and observer .

Dopper's effect is sound in addition of relative velocity between source and observer, also depends while source and observer or both are moving. Doppler effecct in light depennd only on the relative velocity of source and observer. The reason of this is

(A): Apparent frequency is equal to actual frequency when there is no relative motion between source and observer. (R): When there is no relative motion between the source and observer the velocity of sound is zero

Doppler shift in frequency of sound is independent of (Source is moving on the straight line joining source and observer)

(A) Source motion effects the wavelength but observer motion effects the number of waves received by him (B) The apparent change in frequency depends on the distance between source and observer (C) The echo and the direct note differ both in speed and intensity The correct statements are

Under what conditions there will be no Doppler effect or no change in frequency despite the motion of source and/or observer.

Does the Doppler effect increase the intensity of wave when its source approaches the observer?

Show that when the speed of the source and the observer are small compared to the speed of sound in the medium, the change in frequency becomes independent of the fact whether the source is moving or the observer.

(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 ?
