Conceptual Physics Alive: Light Waves

Conceptual Physics Alive: Light Waves includes a digital video and questions set with answers. Observe Paul Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. In this video, the interference of light waves is demonstrated with laser light and related to the colors of thin films. A discussion on polarization is illustrated using polarizing material.
