Question

read this example of absorption.

zach lives in an apartment building. his downstairs neighbors are noisy at night, which makes it hard for him to sleep. so, zach lays a thick rug down on his bedroom floor. this reduces the noise zach hears at night.

how does the rug lower the volume of sound that reaches zachs apartment? complete the sentences.

when sound waves are absorbed by the rug, energy transfers from the
. so, the amplitude of the sound waves that travel into
zachs room
.

Explanation:

Sound waves carry energy, and when a material like a rug absorbs them, the energy from the sound waves is transferred to the rug. The amplitude of a sound wave is directly related to its volume; a smaller amplitude means a quieter sound. As the rug takes energy from the sound waves, the remaining waves that reach the room have less energy, so their amplitude decreases.

Answer:

When sound waves are absorbed by the rug, energy transfers from the sound waves to the rug. So, the amplitude of the sound waves that travel into Zach's room decreases.
