Mention the types of mirrors used as (i) rear view mirrors, (ii) shaving mirrors. List two reasons to justify your answers in each case.

Explanation

(i) Convex mirror is used as rear view mirror in vehicles because
it always produces an erect image of the objects,
the image formed in a convex mirror is highly diminished thus it gives a wide field of view.
(ii) Concave mirrors are used as shaving mirrors because
when the face is held within 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.
