Moire Patterns

For Teachers 9th - 12th
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

For Teachers 9th - 12th
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.
