The Language of Sound
By Cindy Grigg |
|
1 Sound is a form of energy. An object makes sound when it vibrates matter. Matter could be a solid (earth), a liquid (water), or a gas (air). Most of the time, we hear sound that travels through air. Sound energy is transported through waves. A wave travels from one place to another with a certain velocity. Velocity is the speed and direction of the movement.
