Question
Which image corresponds to what moment in time?
(1 point)
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.
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 interpretation of the relationship between sound frequency (pitch) and motion of the sound source is based on the Doppler effect.
1. When a sound source moves **towards** an observer, the sound waves are compressed, resulting in a **higher-pitched** sound (shorter wavelength).
2. When a sound source moves **away** from an observer, the sound waves are stretched, resulting in a **lower-pitched** sound (longer wavelength).
Given this understanding:
The statement that correctly represents these concepts 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."
So the first option is the correct one.
