6.1 Sound Wave

How strong or weak a sound is; it depends on the energy of the sound wave.

The material (like air, water, or a solid) through which sound travels.

The motion of particles in a medium as they vibrate to create sound waves.

Tiny parts of matter (like air molecules) that vibrate to pass sound waves.

How high or low a sound is; it depends on the frequency of the sound wave.

Vibrations that travel through a medium, allowing us to hear sounds.

How fast sound travels through a medium (it’s faster in solids, slower in liquids, and slowest in gases).
