A mirror is a reflective surface that bounces off light-producing either a real image or a virtual image.
There are two types of mirrors:
Plane mirror:
A plane mirror is a flat, smooth reflective surface.
A plane mirror always forms a virtual image that is upright, and of the same shape and size as the object, it is reflecting.
Spherical mirror:
A spherical mirror is a mirror that has a consistent curve and a constant radius of curvature.
The images formed by a spherical mirror can either be real or virtual.
Spherical mirrors are of two types:
Concave:
If a hollow sphere is cut into parts and the outer surface of the cut part is painted, then it becomes a mirror with its inner surface as the reflecting surface.
This type of mirror is known as a concave mirror
When the concave mirror is placed very close to the object, a magnified and virtual image is obtained.
Convex:
If the cut part of the hollow sphere is painted from inside, then its outer surface becomes the reflecting surface.
