Students investigate an example of interference that provides further evidence in support of the wavelike behavior of light.

In this physics classroom, students learn how and why light of certain frequencies can be selectively absorbed, reflected or transmitted.

To understand how bounded waves behave and how reflection of waves affects the wave components.

The operation of Polaroid filters on a pair of sunglasses is shown.

In this experiment, students construct models of larger red and smaller blue waves on index cards, and use them to investigate how light behaves when it is reflected off the front and the back of soap film.

Investigate the constructive and destructive interference of waves as they reflect off the front and back surfaces of soap film. See what colorful effects can be created on a large, vertical soap film surface where gravity comes into play.

This site from Architectural Acoustics and Lighting provides a discussion of various factors affecting the acoustics of a given room. Room dimensions, the wavelength of the sound wave, the physical characteristics of the walls, the...
