Answer 2

${\underline {\underline{\Large {\bf \gray { Required \: Answer } }}}}$

Spherical mirrors :

$\longmapsto$ Mirrors having curved reflecting surface are called spherical mirrors.

There are two types of spherical mirrors :

1. Concave Mirrors
2. Convex Mirrors

Concave Mirrors :

$\longmapsto$ A mirror whose reflecting surface is towards the centre of curvature is called as concave mirror.

›»› Characteristics of concave mirrors :

• Reflecting surface is curved inwards.

• Image formed is real and inverted except when the object is closer to the mirror.

• Image formed is either enlarged or diminished.

Convex Mirrors :

$\longmapsto$ A mirror whose reflecting surface is on the opposite surface of centre of curvature is called as convex mirror.

›»› Characteristics of convex mirrors :

• Reflecting surface is curved outwards.

• Image formed is virtual and erect.

• Image formed is diminished.
