Original Khojo Papers practice question — not from a past board paper.
Answer
A concave mirror is used as a shaving or dentist's mirror, because it gives a magnified erect image when the object is close to it. A convex mirror is used as a rear-view mirror in vehicles, because it always gives an erect diminished image and so covers a wide field of view.
