Curved or spherical mirrors
Definetion- A mirror whose reflecting surface is curved or spherical i.e curved inwards or outwards is called a spherical mirror.
There are two types of mirrors and there name is as follows-:
Let us study both the types of mirrors in detail.
Concave Mirror- A part of the hollow sphere whose outer surface i.e bulgging surface is polished and inner surface or depressed surface acts as reflecting surface is called or known as concave mirror In simple words
The mirror whose reflecting surface curved inwards.
Convex mirror- A part of the hollow sphere whose inner surface i.e depressed surface is polished and outer surface i.e bulgging surface acts as an reflecting surface is called or known as convex mirror.
Those mirrors whose reflecting surface is curved outwards is called convex mirror.
Important terms in in or with respect to spherical mirrors
Center of Curvature- Center of curvature is the center of the hollow sphere of which the spherical mirror forms a part, In simple words
The spherical mirror was a part of a hollow sphere before cutting it from hollow sphere and the center of that hollow sphere is called as COC or Center of curvature
Radius of Curvature- The radius of the hollow sphere of which the spherical mirror forms a part is called radius of curvature of that spherical and note that it is denoted by Capital R.
Pole- Mid point of spherical mirror and note it is denoted by P.
