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

Text Solution

Verified by Experts

(i) No, change in frequency due to Doppler effect has nothing to do with distance between source and listener.
(ii) Yes, in case of sound waves. No, in case of light waves.
