A person moves away from a stationary sound source. Which phrase describes the sound perceived by the person?(1 point)

Question

Responses

higher pitch and shorter wavelength
higher pitch and shorter wavelength

higher pitch and longer wavelength
higher pitch and longer wavelength

lower pitch and longer wavelength
lower pitch and longer wavelength

lower pitch and shorter wavelength

Answer 1

When a person moves away from a stationary sound source, the sound waves are stretched, which causes the frequency to decrease. A lower frequency corresponds to a lower pitch and longer wavelength. Therefore, the appropriate response is:

lower pitch and longer wavelength.
