Question

Which of the following mirror is used by a dentist ​

Answer 1

So dentists use concave mirror to examine small cavity. ∆Since, the concave mirror forms a virtual, erect but magnified image of the object when the object is placed at a distance smaller than focal length of mirror. So dentists use concave mirror to examine small cavity.

Answer 2

A concave mirror gives the dentist a magnified reflection of the mouth while also refracting a bit of light. This means the image in the mirror is larger, brighter, and, for the dentist, easier to see. Another plus of using a concave mirror is that the image in the mirror isn't inverted.
