Seeing Interference Fringes with a Telescope
Students construct an interferometer using a simple telescope. In this physics lesson, students explain how light waves create the fringe patterns. They observe patterns made by different objects in the sky and compare them.

Polarization
Eighth graders study the basic facts of polarization. In this light waves lesson students demonstrate some activities illustrating interference patterns.
Curated OER
Frozen Film
Young scholars discover how light reflects off surfaces. In this hands-on demonstration, students examine how variations in color are produced by light interference.
Curated OER
Frozen Film
Students are introduced to the topic of light interference through this hands-on activity. They observe how light reflects off two surfaces and then meets to form an interesting variation of color on a film surface.
