Physics Demo Manual

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.

Flash Light Radio Purpose: To demonstrate basic properties of modulated electromagnetic wave and introduce the basic of fiber optic transmission lines. Procedure: Hook up an audio source (Walkman, radio or CD player) to an amplifier and feed the amplifier output to a flashlight. Adjust the volume to have flashlight bulb shine brightly. Connect the output of the solar cell to an amplifier and the amplifier output to a speaker. Point the Walkman driven flashlight to a solar cell and listen to the music coming out of the speakers. Hints: With an incandescent light bulb the quality of transmission is poor but the idea comes across nicely.
