1 Tuning Forks Lab Review

2 Understanding Tuning Forks Higher the Pitch Greater the Frequency = Higher the Pitch Higher the frequency = the faster it vibrates Highest lowest= 480Hz, 426.7Hz, 384Hz, 341.3Hz, 320Hz, 288Hz. LOUDNESS is not the same as High Pitch LOUDNESS is not the same as High Pitch

3 Mediums The space that sound waves moves through. Examples: Air, Helium, Wood, etc. Thin surfaces Sound is louder, but does not vibrate very long. Thick surfaces Sound 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. Water When a vibrating tuning fork is placed in a cup of water, the energy from the fork is transferred into the water. When 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.
