Answer 1

The mirror used by a dentist to examine the teeth of a person is concave.

Explanation:

A dentist uses a concave mirror because it can produce a highly magnified and erect (upright) image when an object is held very close to it. By positioning the patient’s tooth within the focal length of the mirror, the dentist gets a larger, clearer view of tiny cavities or damage. It also helps converge ambient light directly onto the tooth to improve overall visibility inside the mouth
