Solution

A convex mirror has a wider field of view, and always forms virtual, erect and small-sized images of a large number of objects at the same time. Size of the image formed by a plane mirror is equal to the size of the object; hence, it has a small field of view as compared to the convex mirror. Thus, a convex mirror is used as a rear view mirror in a car.
