Question

A concave mirror is used as a head mirror by ENT specialists. The same mirror can also be used as a shaving mirror. Why?

Answer 1

Answer:

This is the reason why ENT specialists use it as a head mirror. The concave mirror is used as a shaving mirror because when an object is held between the pole and principal focus of a concave mirror, it forms a virtual, erect and magnified image of an object.

Concave mirror is used as shaving mirror. This is because it produces a virtual, erect and magnified image of our face when held in front of the face at a distance less than its focal length thus, allowing us to observe our face closely.
