Question

Reeta asked her teacher that which materials cannot be used to make a lens? What will be the answer given by

teacher to her?​

Answer 1

Answer:

Option D) Clay,

Reason: clay is not transparent or translucent to the kind of light we can see, and when we can't see through something how can it be a lens? Also water is not the right answer because it can refract light and hence can be used as a lens but we don't use it because it can destroy even the normal image....
