Science mirror and lens

Question 1

What is a mirror?

Answer 1

A mirror is an optical device usually made of glass and a smooth reflective surface with
one side polished with a thin layer of metal, that allows for the reflection of light.

Question 2

What is a reflection principle

Answer 2

when light rays fall on a mirror, they get
reflected from its surface at the same angle at which they were incident. When these
reflected rays fall in the eyes of the viewer, they appear to be coming from the back of
the mirror, forming an image behind the mirror.

Question 3

What are Plane Mirrors

Answer 3

These mirrors are flat, having a reflective coating at the back. They
form virtual, upright images of the same size as the object. Plane Mirrors are
commonly used as dressing mirrors.

Question 4

What are Concave Mirrors

Answer 4

These curved mirrors have an inward curve on the reflecting side.
They can produce real and upright or virtual and inverted images, of different sizes,
depending upon the position of the object. Concave Mirrors are used as makeup
mirrors, solar power plants and telescopes.

Question 5

What are Convex Mirror

Answer 5

These curved mirrors have an outward curve on the reflecting side.
They produce diminished, virtual and upright images. Convex Mirrors are frequently
used as rear-view mirrors in vehicles, wide-view mirrors in stores and in optical
instruments for magnification
