Step-by-step explanation:

Doppler effect

The increase and decrease of the frequency of sound, light waves due to the proportional motion between the source of the wave and its receivers, Doppler effect is the quantitative analysis that shows how the repetition heard by the stable perceiver depends on whether the perceiver sees the source approach.

This means that waves have dissimilar perceived frequencies when the wave source is in motion.
