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:

clay because it is not transoarent lens if the lens is made up of clay the light rays cannot pass . plastic and clay as it does cannot refract light.

In addition to crown glass and flint glass, modern day lens makers use quartz crystals and acrylic plastic. These materials may be used in combination.

There is some plastic that is transparent so the plastic can be used to make a lens but the clay is a opaque material so the light can't transmit through it so clay can't be used for making the lens.
