higher pitch and shorter wavelength
higher pitch and shorter 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 perceived by the person will have a lower pitch and longer wavelength. This effect is due to the Doppler effect, which causes the frequency of the sound waves to decrease (resulting in a lower pitch) and the wavelength to increase (resulting in a longer wavelength) as the observer moves away from the source.

So, the correct response is: lower pitch and longer wavelength.
