Real and Virtual images
1. In a concave mirror, the focus is real.
The object and the image lie on the same side of the
mirrored surface. A real image is called so because it
can be caught on a screen.
2. In a convex mirror, on the other hand, the object and
its image lie on the opposite sides of the mirrored
surface. The image therefore is a virtual image.
It cannot be captured on a screen.
3. In a plane mirror, the image again is a virtual one, as
it does not form on the same side as that of the
object.

What is a spherical mirror?
Spherical mirrors are mirrors whose surfaces form a part of a hollow sphere, The spheres can be made of glass or any polished metal surfaces
Types of spherical mirrors :
1. Convex Mirror
2. Concave Mirror
Convex mirror :. If the mirror coating is in the inside of the spherical surface, then the mirror is called a convex mirror
Concave mirror :If the mirror coating is on the outside of the spherical surface, then the mirror is called a concave mirror.
