DOPPLER'S EFFECT WHEN SOURCE AND OBSERVER ARE NOT IN SAME LINE OF MOTION

Is there a Doppler's Effect for sound when the observer or the source move at right angles to the line joining them?

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 .

Assertion: The whistle of an approaching engine appears to be shriller than that of a receding engine. Reason: This is due to Doppler effect, which states that if a source of sound approaches the observer, the frequency of sound increases and if the source recedes the observer, the frequency of sound decreases.
