IT IS DEFINED AS THE INTERFERENCE OF PLANE CoVEX LENS AND PLANE GLASS PLATE.
NEWTON RING ARE FORMED BETWEEN THE INTERFERENCE INIREFLECTED LIGHT FROM LOWER PART OF PLANE CONVEX LENS AND UPPER PART OF PLANE GLASS PLATE.
NEWTON RING
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 first studied the effect in 1717. When viewed with monochromatic light, Newton's rings appear as a series of concentric, alternating bright and dark rings centered at the point of contact between the two surfaces. When viewed with white light, it forms a concentric ring pattern of rainbow colors, because the different wavelengths of light interfere at different thicknesses of the air layer between the surfaces.
