Teaching About Energy

This publication deals with how the human eye perceives color and how that color perception is triggered by the light sources and objects of our world. The colors of soap bubbles and other thin films are treated in more than usual detail, and the approach is extended to explain the colors of transparent materials sandwiched between polarizers.

A tonic for lagging interest in the spring semester, the resource book incor-porates many laboratory activities and demonstrations, including some new ones, important commercial applications, sample questions, and Physics Olympics events.
