Question

State the major differences between
Doppler effect in sound and Doppler effect in
light.​

Answer 1

$\huge\underline{\underline\mathtt{Answer:-}}$

(1) In case of Doppler shift for light waves, only the relative velocity between the observer and the source matters irrespective of who is in motion

(2) In case of light, classical and relativistic Doppler effects are different. In case of sound, it is only classical.

(3) We must know whether the observer or the source is in motion; to obtain the Doppler shift for sound waves.

(4) The velocity of wind changes the speed of sound, in turn affecting the Doppler shift. In this case, the component of wind velocity along the line joining the source and observer is considered. This is algebraically added to the velocity of sound.
