Answer 1

When wave energy like sound or radio waves travels from two objects, the wavelength can seem to be changed if one or both of them are moving. This is called the Doppler effect. ... This effect is readily observable as variation in the pitch of sound between a moving source and a stationary observer.

Answer 2

According to Doppler's effect , whenever there is a relative motion between a source of sound and listener , the apparent frequency of sound is different from the actual frequency.
