Doppler effect- Description

Hello, There!

The Doppler effect,, describes the changes in frequency of any kind of sound or light wave produced by a moving source with respect to an observer.

Explanation:

Waves emitted by an object traveling toward an observer get compressed — prompting a higher frequency — as the source approaches the observer
