A bi-convex lens is formed with two thin plano-convex lenses as shown in the figure. Refractive index n of th efirst lens is 1.5 and that of the second lens if 1.2 Both the curved surfaces are of the same radius of curvature `R=14cm. ` For this bi-convex lens, for an object distance of 40cm, the image distance will be  img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V04_C01_E01_504_Q01.png" width="80%"
