Answer 1

The correct phrase that describes the sound perceived by a person moving away from a stationary sound source is lower pitch and longer wavelength.

This phenomenon is due to the Doppler effect, where the frequency of the sound waves decreases as the observer moves away from the source, resulting in a lower pitch. Additionally, a lower frequency corresponds to a longer wavelength.
