Looking at Sound Presented by
Activity: Dancing Salt MathScience Innovation Center 2010
A form of energy produced and transmitted by vibrating matter. Vibration: back and forth movement of molecules It travels in waves. Sound MathScience Innovation Center 2010
Waves Complete to and fro movement There and back Full cycle MathScience Innovation Center 2010
How many full cycles? 3 cycles 3 waves MathScience Innovation Center 2010
Wavelength • the distance between one part of a wave and the same part of the next wave. MathScience Innovation Center 2010
Demonstration: Coil Spring MathScience Innovation Center 2010
Frequency • the number of waves moving past a point in one second. MathScience Innovation Center 2010
low time Which sound do you think has the higher frequency? high time MathScience Innovation Center 2010
Pitch • the measure of how high or low a sound is. • depends on the frequency of a sound wave. MathScience Innovation Center 2010
low time Which sound do you think has the higher pitch? high time MathScience Innovation Center 2010
soft time Which sound do you think sounds louder? time loud MathScience Innovation Center 2010
