Use the images to answer the question.

The images show the pressure waves created by a passing sound source.

The compactions and rarefactions are at a larger distance in the pressure wave in the air for a low-pitched sound than in a high-pitched sound. Also, the number of compactions and rarefactions is more in a high-pitched sound.

Which image corresponds to what moment in time?

The low-pitched sound corresponds to the sound source getting closer; its wavelength is shorter. The high-pitched sound corresponds to the sound source moving away; its wavelength is longer.
The low-pitched sound corresponds to the sound source getting closer; its wavelength is shorter. The high-pitched sound corresponds to the sound source moving away; its wavelength is longer.

The correct response based on the explanation given is:

The low-pitched sound corresponds to the sound source moving away; its wavelength is longer. The high-pitched sound corresponds to the sound source getting closer; its wavelength is shorter.

This is consistent with the description that low-pitched sounds have longer wavelengths (which means they are spaced further apart) and that high-pitched sounds have shorter wavelengths (which means they have more frequent compressions and rarefactions).
