Two polarizing sheets are oriented 90 degrees with respect to one another and placed on the overhead projector and it is shown that no light gets through. When a third sheet is placed between the two, some light gets through depending on the relative orientation of that third sheet. If the third sheet is removed and placed on top of the first two crossed polarizers, it is observed that no light gets through.
Equipment:
- Three polarizing sheets
- Overhead projector
- Screen
