1.	What is the Newton's fringe are called?
Answer» Answer: NEWTON's rings is a phenomenon in which an interference pattern is CREATED by the reflection of light between TWO surfaces—a spherical surface and an adjacent touching flat surface. It is named for Isaac Newton, who investigated the effect in his 1704 treatise Opticks.This RESULTS in a pattern of concentric bright and dark rings, interference fringes. Newton's rings seen in two plano-convex lenses with their flat surfaces in contact. ... In white light, the rings are rainbow-colored, because the different wavelengths of each color INTERFERE at different locations.
