A monochromatic source of light is kept at the focus of a condensing lens. These rings are known as Newtons rings. When a plano convex lens of long focal length is placed over an optically plane glass plate a thin air film with varying thickness is enclosed between them. Diameter of the central ring R1 R2 R3 Figure 83. The apparatus for Newtons ring and the aim of the experiment are to study the formation of Newtons rings in the air-film in between a lens which is a plano-convex and a glass plate by using a nearly monochromatic light from a sodium-source and hence this is to determine the radius of curvature of the plano-convex lens.
