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


Best Answer

Ans. (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.
