Newton Ring Apparatus – MAS 4113
This simple apparatus nicely demonstrates Newton’s rings. It consists of a slightly convex lens, mounted against a flat glass plate. Interference fringes, known as Newton’s rings, can be observed as a series of light and dark concentric circles around a central dark spot where the lens and glass plate meet. This phenomenon is usually observed using a monochromatic light source such as a sodium lamp. The pressure on the glass can be varied by usin.. 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.
