Question

Doppler shift in frequency does not depend upon

(a) the frequency of the wave produced

(b) the velocity of the source

(c) the velocity of the observer

(d) distance from the source to the listener

Answer 1

(d) distance from the source to the listener

Change of frequency due to the Doppler effect is

\(\bar{n}=n(\frac{v-v_0}{v-v_s}).\)

This is independent of distance between source and observer.
