Sound waves

Vibration

A movement shaking back and forth

High pitches

High pitches vibrate faster and have a high frequency (speed). Long objects have loud pitches and high vibration

Energy

The ability to cause change or make things move

sound

a form of energy that is made by vibration. It can be heard by a sound receptor (ears, animals, and machine receptors)

Amplitude

how tall the wave is. The taller the wave, the more energy it has. A loud volume has a tall amplitude.

Sound receptors

something that hears a sound. Can be human, animal, or machine.

Pitch

the highness or lowness of a sound. The longer the length, the lower the pitch. The shorter the length, the higher the pitch.

volume

the loudness or softness of a sound. If you want to increase the volume, you need to give the sound more energy. For example, strum the guitar harder

Frequency

the number of vibration in a given time. For example, speed

Sound wave

travels in all directions. Sound waves are like ocean waves
