A plano convex lens has index of refraction n The curved side of the lens has radius of curvature R and rests on a flat glass surface of the same index of refraction with a film of index nfilm between them as shown in Fig 37 18a The lens is illuminated from above by light of wavelength A Show that the dark Newton s rings have radii given approximately by m R n film
