Answer:
Both the convex and concave mirror is a part of an imaginary sphere. The fundamental difference between them is that the reflective surface of a concave mirror is inside the sphere and that of a convex mirror is outside.Convex mirror:
The outer surface of the spherical mirror is reflecting.
It forms virtual and erect images.\
The image formed is always smaller than the actual size.
Its focus point lies at behind its reflecting surface
Concave mirror:
The inner surface of the spherical mirror is reflecting.
It forms a real-inverted image and also virtual-erect pictures.
The image formed can be larger or smaller than the actual size.
Its focus point lies at the front of its reflecting surface
Note: Students usually confuse which is concave and which is convex. So remember that the front part of a spoon is concave and the back part of a spoon is convex.
