Question

Group of answer choices

an increase in the frequency of the sound wave

a decrease in the frequency of the sound wave

an increase in the amplitude of the sound wave

a decrease in the amplitude of the sound wave

Answer 1

When a sound source is moving toward the observer, the observer will hear a higher pitch due to an increase in the frequency of the sound wave. This phenomenon is known as the Doppler effect, where the relative motion between the source of the sound and the observer causes a change in the frequency of the sound waves perceived by the observer.
