Q. Doppler’s effect in sound in addition to relative velocity between source and observer, also depends while source and observer or both are moving. Doppler effect in light depends only on the relative velocity of source and observer. The reason of this is
A) Einstein’s mass – energy relation
B) Einstein’s theory of relatively
C) Photoelectric effect
D) None of these
