Answer 1

Answer:

Mirror = A mirror is a reflective surface that light does not pas through, but bounces off of and this produces an image. Mirrors are made by putting a thin layer of silver nitrate or aluminium behind a flat piece of glass. When you place an object in front of a mirror, you see the same object in the mirror.

Explanation:

Lens = lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A simple lens consists of a sinagle piece of transparent material, while a compound lens consists of several simple lenses, usually arranged along a common axis.
