Sound is a type of energy that travels in waves through air, water, or solids. When a sound wave hits an object, it can be reflected, absorbed, or transmitted. Reflection occurs when a sound wave bounces off a surface and returns to its original direction.

Sound waves can travel through solids, liquids, and gases. They travel fastest and with the least resistance through solids. Reflection of sound waves can be used to measure the distance between two objects. This method is called echolocation. Sound waves can be absorbed by materials such as cloth, foam, and fiberglass to reduce noise pollution.
