Lens-Maker Formula: A double-convex thin glass lens has equal-magnitude radii of curvature. The focal length of this lens is +31.2 cm and the index of refraction of the glass is 1.52. The lens is to be replaced with a plano-convex glass lens of the same focal length and thickness. The radius of curvature of the convex surface of the replacement lens is 13.0 cm. What should be the index of refraction of the glass of the plano-convex lens?
