What happens to sound when it travels through different materials?

Back

Sound travels at different speeds through different materials. It travels fastest in solids, slower in liquids, and slowest in gases.

Front

What is pitch?

Back

Pitch is how high or low a sound is. It is determined by the frequency of the sound waves.

Front

What is volume?

Back

Volume is the loudness or softness of a sound. It is determined by the amplitude of the sound waves.

Refraction is the bending of light as it passes from one material to another, like from air to water.

A sound wave is a wave that is created by vibrating objects and travels through air, water, or solids.
