DVW08 - Beat Frequencies, Tuning Forks

Objective:

To illustrate the production of beats.

 
Apparatus:  
  • Tuning forks on resonance cases
  • Clamp
  • Rubber hammer


Method:

The procedure is identical to DVW7, except that the clamp is adjusted to a slightly different frequency then that of the other fork. The difference between the frequencies is detected as the "Beat" frequency.
