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 2

The most probable answer which will be given by her teacher,is as follows -

• The opaque materials cannot be used to make optical lens.

• The light rays pass through the transparent optical lens to perform the necessary refraction activities.

• Now,if we use opaque materials for making lens,the light rays will be unable to pass through the lens and necessary refraction activities by that lens will not happen anymore.
