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