Additional Details
Newton's Rings are the interference pattern seen when light passes through two glass pieces, one convex and the other flat, pressed together.
The colorful rings that result from this simple arrangement, even in normal room light, are quite amazing, and will prompt discussions of light interference, refraction, and the visible spectrum. Apparatus consists of glass plates 1.6 inch (40mm) in diameter, visible 1.33 inch (34mm) in a frame, adjusted with three screws.
