Explanation:
Detailed explanation-1: -The Doppler effect is an alteration in the observed frequency of a sound due to motion of either the source or the observer. The actual change in frequency is called the Doppler shift.
Detailed explanation-2: -The Doppler effect, or Doppler shift, describes the changes in frequency of any kind of sound or light wave produced by a moving source with respect to an observer. Waves emitted by an object traveling toward an observer get compressed-prompting a higher frequency-as the source approaches the observer.
Detailed explanation-3: -The Doppler effect is the change in observed frequency of a wave due to relative motion of the source and observer.
