उत्तर
- Concave mirror: Concave mirrors can form an enlarged image of an object. Therefore, dentists use them to see the enlarged image of the patient’s teeth.
- Convex mirror: A convex mirror forms a diminished and upright image of an object. It is used as a side view mirror of the car because it enables the driver to view objects spread over a large area behind him/her.
