Experiment Ol-17
Newton's Rings
Description: A
plano-convex lens with a long focal length is mounted with its curved side against
an optically flat piece of plane glass to produce an axially symmetric air wedge
between the lens and glass plate. The system is illuminated by a laser
and projected onto a screen to show colored circles. The circles are colored
because the interference condition is satisfied differently for different wavelengths.
