Question

9.One half of a convex lens is covered with a black paper. Will the lens produce a complete image of the object.
Verify your answer experimentally.
Explain ur observation.​

Answer 1

Explanation:

Yes it will. Even if half of the convex lens is covered with black paper, the lens will produce a complete image. however the intensity of the image may be less. It can be observed experimentally by using a lighted candle and a convex lens...

Hopes it help you❤️❤️

Answer 2

Answer:

Covering a part of the lens with an opaque object does not hinder the formation of the image.

But the image formed will be less brighter and less sharper due to the loss of a few refracted rays from the covered part of the lens.

Experimentally we can use a convex lens and cover one half of the lens with a black paper(opaque object) and emit light with a simple torch.

The resultant observation will be same as the explanation of the phenomenon.

i.e. the image formed will be less brighter and less sharper due to the loss of a few refracted light rays from the covered part of the lens.

Hope this answers your query.
