Question

Dentist uses this mirror to examine teeth of patients.

• A. Concave mirror
• B. Convex mirror
• C. Plane mirror
• D. None of the above

Answer 1

The Correct Option is A

To solve the problem, we need to identify which type of mirror is used by dentists to examine the teeth of patients.

1. Understanding Mirror Properties:
- Concave mirror: Forms enlarged, erect images when the object is close. This helps dentists see a magnified view of teeth and gums.
- Convex mirror: Always forms diminished, virtual images. Used in vehicles for a wider field of view.
- Plane mirror: Forms images of the same size as the object, not magnified.
- None of the above: Incorrect since concave mirrors are indeed used.

2. Reason Dentists Use Concave Mirrors:
Concave mirrors focus light and magnify the image, making it easier for dentists to see small details inside the mouth.

Final Answer:
The correct mirror used is the Concave mirror (Option A).
