of a wave due to the motion of the source and/or receiver.

Yes indeed, that is a true statement.  Truer words are seldom written, and I could not agree with you more.

In case you are asking a question, I can kind of see how this might be a question if there is a blank after "... the change in ..." that is to be filled with one or more new words.

If that is the situation, then the blank can be filled with "frequency or wavelength" .

The Doppler effect is the change in the wavelength (or frequency) of energy in the form of a wave due to the motion of the source and/or receiver.

What is the Doppler effect?

  • Doppler effect is the change in energy wavelength (or frequency) in the form of waves, for example, sound or light.
  • As a result of the motion of either the source or the receiver of the waves, the effect is named for the Austrian scientist Christian Doppler, who demonstrated the effect for sound.
  • If the source of a wave is moving towards a receiver, the frequency at which the waves are received is higher than the frequency at which they are sent out.
  • The formula of the Doppler effect is,

                                             f’ = f (c + vr) / (c + vs)

where,

  • f’ = apparent frequency
  • f = actual frequency
  • c = speed of sound waves in the medium
  • vr​ = velocity of the receiver/observer with respect to the medium
  • vs​ = velocity of the source with respect to the medium
