Question

One-half of a convex lens is covered with a black paper. Will this lens produce a complete image of the object? Verify your answer experimentally. Explain your observations.

Answer 1

The half of the convex lens is covered with black paper can be produce a complete image as well as observed experimentally by using a lighted candle and a convex lens lighted candle and place it in front of a convex lens mounted form the plane surface as well as candle along the axis of the plane and obtained the convex lens mounted on a plane surface.

Answer 2

Yes, it will produce a complete image of the object, as shown in the figure. This can be verified experimentally by observing the image of a distant object like a tree on a screen when the lower half of the lens is covered with a black paper. However, the intensity or brightness of the image will reduce.
