Moire Patterns
By overlapping combs and window screening and by looking at a printed set of consecutively larger circles, learners observe Moire patterns, which provide a visual of what happens during wave interference.

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.

The Physics Classroom: Light Waves and Color
The behavior of light waves is introduced and discussed. Also, polarization, color, diffraction, and interference are introduced and discussed thoroughly as supporting evidence of the wave nature of light.

Physics Classroom
The Physics Classroom: Light Waves and Color: Two Point Source Interference
Students examine the findings of Thomas Young's light experiment, which showed that an interference pattern results when light from two sources meets up while traveling through the same medium.
