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?

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

To analyze the scenario presented with sound waves, we need to consider the characteristics of low-pitched and high-pitched sounds, as well as the Doppler effect:
1. **Low-pitched sounds** have longer wavelengths and are represented by fewer compactions and rarefactions in a given distance.
2. **High-pitched sounds** have shorter wavelengths, resulting in more compactions and rarefactions in the same distance.
3. When a sound source moves away from the observer, the sound waves are stretched out, leading to a lower frequency (lower pitch), while when it approaches, the wavelengths are compressed, leading to a higher frequency (higher pitch).
Given the options and the information provided, here’s the right interpretation:
- If a low-pitched sound is observed while the sound source is moving away, it has a longer wavelength.
- Conversely, if a high-pitched sound is observed while the sound source is moving closer, it has a shorter wavelength.
Therefore, the correct response 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.**
