Physics Demo Manual

Demonstrations are cataloged according to PIRA Bibliography

PLEASE REQUEST DEMOS WELL IN ADVANCE

Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

Resonant Chambers

Purpose:

To show the excitation of various sized spherical chambers by using tuning forks as sources.

Procedure:

The chambers may be excited by striking the tuning fork of proper frequency and then holding it near the chamber opening. Exciting the chambers with other than the proper frequency will yield no results.

Hints:

Choose tuning forks with matching resonator frequencies and maybe one which doesn't match at all
