Name two spherical mirrors. Define them. Write any three points of difference between them.

(N/A) The two spherical mirrors are: $(i)$ Concave mirror and $(ii)$ Convex mirror.
$(i)$ Concave mirror: $A$ spherical mirror whose reflecting surface is curved inwards,i.e.,faces towards the center of the sphere,is called a concave mirror.
$(ii)$ Convex mirror: $A$ spherical mirror whose reflecting surface is curved outwards is called a convex mirror.
Points of difference:
$(1)$ The reflecting surface of a concave mirror is curved inwards,whereas the reflecting surface of a convex mirror is curved outwards.
$(2)$ $A$ concave mirror can produce both real and virtual images,whereas a convex mirror always produces virtual and erect images.
$(3)$ The image formed by a concave mirror can be enlarged,diminished,or of the same size as the object. The image formed by a convex mirror is always diminished.
