Purpose: To demonstrate sounds produced by tuning forks including beats, and show that the sound is amplified when the tuning fork is                      attached to a resonator.

1. With the clamp removed, strike one of the tuning forks. Then, stop the first tuning fork from ringing and hear that the second tuning fork.
2. Place the clamp on one of the tuning fork's tines. Strike both tuning forks and hear the beat frequency. Adjust the clamp position to increase or decrease the difference in the frequencies. The computer can also be used to display the sound patterns with a sound sensor (see W04).
