Question 7

What are the lenses?

Answer 7

➤ A lens is an optical device that is used to bend light in a specific way.

Question 8

What are the Lenses that are classified into two types.

Answer 8

Lenses are classified into two types.

_A converging lens bends light so that the light rays come together to a point.

_A Diverging lens bends light so it spreads light apart instead of coming together.
