What is absorption in the context of sound waves?

Back

Absorption is the act of taking in sound energy and not reflecting or throwing it back. It occurs when sound waves enter a material and are converted into other forms of energy.

What is a vacuum?

Back

A vacuum is a space devoid of matter, where sound cannot travel because there are no particles to transmit the sound waves.

Front

How do sound waves travel through different mediums?

Back

Sound waves travel through solids, liquids, and gases, but they travel fastest in solids due to closely packed particles.
