Question -

One-half of a convex lens is covered with a black paper.



Answer -

Will this lens produce a complete image of the object? Verify your answer experimentally. Explain your observations.

Answer
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.
