A convex lens of radii of curvature 20cm and 30 cm respectively. It is silvered at the surface which has smaller radius of curvature. Then it will behave as `(mu_(g) = 1.5)`

A plano convex lens (n = 1.5) and radius of curvature 20 cm is silvered at the curved surface. What is the power of the system ?

A concavo-convex glass (index=1.5) lens has radii of curvatures 60cm and 40cm, respectively. Its convex surface is silvered , and its placed on a horizontal table with concave surface up. The concave surface is then filled with a liquid of index 2.0. The combination behaves like

The concave surface of a thin concavo-convex lens of index 1.5 has radius of curvature 50cm and 10cm respectively.The concave side is silvered andplaced on a horizontal surface as shown Focal length of silvered lens is:
