Question #74819
Newton’s rings are formed with reflected light of wavelength 589 nm using a plano-
convex lens and a plane glass plate with a liquid between them. The diameter of the
15th ring is 5.1 mm and radius of curvature of the curved surface of the lens is 1 m.
Calculate the refractive index of the liquid if the ring is dark.
