Explanation:
Detailed explanation-1: -Doppler’s effect is applicable to both light and sound waves. According to Doppler’s effect, whenever there is a relative motion between a source of sound and listener, the apparent frequency of sound heard by the listener is different from the actual frequency of sound emitted by the source.
Detailed explanation-2: -Besides sound and radio waves, the Doppler effect also affects the light emitted by other bodies in space. If a body in space is “blue shifted, ‘’ its light waves are compacted and it is coming towards us. If it is “red shifted” the light waves are spread apart, and it is traveling away from us.
