Answer:
(1) Convex mirror is used as rear view mirrors
Reasons : (a) It forms an erect image of an object, hence objects become easily identified
(b) It forms a diminished image of object-thus increases the field of vision.
(2) Concave mirror are used as shaving mirrors
Reason : When the face is held with in the focus of a concave mirror, then an enlarged image of the face is seen in the concave mirror. This helps in making a smooth shave
