  2. Understanding Tuning Forks • 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

  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. • 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.
