Question

PLEASE ANSWER ASAP!!!

The compressions in a sound wave are very close together, and the energy supplied by the vibrating source decreases. Which statement best describes how this will affect the wave and what you hear?

The wavelength will decrease, and the sound will become quieter.
The amplitude will decrease, and the sound will become quieter.
The frequency will decrease, and the pitch will become lower.
The intensity will decrease, and the pitch will become lower.

Answer 1

Explanation:

The correct statement is: The amplitude will decrease, and the sound will become quieter.

When the compressions in a sound wave are very close together, the amplitude of the wave decreases. Amplitude is the measure of the maximum displacement of the particles of the medium from their rest position. As the amplitude of the wave decreases, the energy supplied by the vibrating source decreases, and the sound becomes quieter.
