2 Understanding Tuning Forks Greater the Frequency = Higher the PitchHigher the frequency = the faster it vibratesHighestlowest= 480Hz, 426.7Hz, 384Hz, 341.3Hz, 320Hz, 288Hz.LOUDNESS is not the same as High Pitch
3 Mediums The space that sound waves moves through. Examples: Air, Helium, Wood, etc.Thin surfacesSound is louder, but does not vibrate very long.Thick surfacesSound is quieter, but vibrates for a longer period of time.
4 Size of tuning fork? Tine: the length of the tuning fork. The lower frequency tuning forks have longer tines while higher frequency forks have shorter tines.Shorter the tuning fork, the faster it vibrates =higher the pitch it will be.
5 Tuning Forks vs. WaterWhen a vibrating tuning fork is placed in a cup of water, the energy from the fork is transferred into the water.If the fork just touches the water, a small amount of water from the top gains kinetic energy and splashes out.If you dip the fork deeply in the water, the vibrations stop.
