Sound waves are energy that move through air, water, and other materials. The energy can be reflected, absorbed, or transmitted when it encounters a different surface or material. Different materials and surfaces influence how the sound wave will behave.

Reflection: The bouncing of a sound wave off a surface. Absorption: The process in which sound waves are taken in by a material. Transmission: The process of a sound wave passing through a material without being reflected or absorbed.

Sound waves travel faster in some materials than in others. For example, sound travels 4.3 times faster in water than in air! A listener can determine the location of a sound source by using the difference in time it takes for the sound to reach each ear. In some cases, sound waves can be used to see inside of objects! This is called ultrasound imaging.
