A bi convex lens is formed with two thin plan convex lenses as shown in the figure Refract index n of the first lens is 1 5 and that of second lens is 1 2 Both the curved surfaces are the same radius of curvature R 14 cm For bi convex lens for an object distance of 40 c the image distance will be n 1 5 n 1 2 R 14 cm
