Newton s rings are formed by light reflected normally from a plano convex lens and a plane glass plate with liquid between them The diameter of n ring is 2 18 mm and that of n 10 ring is 4 51 mm Calculate the RI of the liquid given that the radius of curvature of the lens is 90 cm and wavelength of light is 5893 A
