Reasoning: Doppler effect:
It is the compression or extension of a sound wave, which causes a change in its wavelength/ frequency. If an object is moving away froma source of sound, the nodes of the wave hit the object at longer intervals than the emitted wavelength. If it is moving towards it then the wavelength is shortened.
Example:
Change in pitch of a siren on a police car as it drives past.
