Sound• A form of energy produced and
transmitted by vibrating matter.– Vibration: back and forth movement of
molecules
• It travels in waves.

Waves• Complete to and fro movement
• There and back
• Full cycle

Pitch
MathScience Innovation Center 2010
• the measure of how high or low a sound is.
• depends on the frequency of a sound wave.
