Demonstrations are cataloged according to PIRA Bibliography


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.

Polarization by Reflection


To demonstrate that a reflected glare is polarized and can be blocked by a polarizer.


Set up a table incandescent bulb lamp pointing on the surface of the bench. Position a smaller CCD camera pointing at the reflected glare. Demonstrate that putting a polarizer between the bench and incident light beam or between a glare and the camera can block the reflected glare light.
