NEWTON RINGS<br />
Interference Pattern Caused By Light Reflection<br />
When a convex lens is placed on a flat plane lens, an air film of gradually increasing thickness outward is formed creating a series of concentric rings.  Each interference fringe indicates an additional distance of a half-wave length between the lenses.
