Uses of concave mirrors

(I) concave mirror are used as shaving mirrors. This is because when the face is placed close to a concave mirror ( so that the face is within its focus ) the concave mirror produces a magnified and erect image of the face. Since a large image of the face is seen in the concave mirror, i becomes easier to make a smooth shave.

(ii) concave mirrors are used by dentists to see the large image of the teeth of patients. This is because when a toot is within the focus of a concave mirror, then an enlarged image of the tooth isseen in the mirror. Due to this, it becomes easier to locate the defect in the tooth.
