The flat face of a plano-convex lens of focal length 10 cm is silvered. A point source placed 30 cm in front of the curved surface will produce a

The plane surface of a plano-convex lens of focal length f is silvered. It will behave as

The plane surface of a plano-convex lens of focal length f is silvered. It will behave as

The plane surface of a plano-convex lens of focal length 60 cm is silvered. A point object is placed at a distance 20 cm from the lens. Find the position and nature of the final image formed.

The plane surface of a plano-convex lens of focal length 60 cm is silvered. A point object is placed at a distance 20 cm from the lens. Find the position and nature of the final image formed.

A plano-convex lens of focal length 30 cm has its plane surface silvered. An object is placed 40 cm from the lens on the convex side. The distance of the image from the lens is

A plano-convex lens (f = 20 cm) is silvered at plane surface. Now focal length will be

A convex lens of focal length 10 cm is placed coaxially 5 cm away from a concave lens of focal length 10 cm. If an object is placed 30 cm in front of the convex lens, find the position of the final image formed by the combined system.

A convex lens of focal length 10 cm is placed co-axially 5 cm away from a concave lens of focal length 10 cm . If an object is placed 30 cm in front of the convex lens, find the position of final image formed by the combined system.
