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.

Open in App

Solution

Every part of a lens forms an image.

For formation of image we require only two light rays to converge.

Therefore, if the lower half of the lens is covered, it will still form a complete image.

However the intensity of the image will be reduced.
