Question

Doctors use a mirror to see the enlarged view of ears, eyes, nose and throat. It is also used by dentists to examine teeth. Name the mirror.

• A. Convex mirror
• B. Plane mirror
  
• C. Concave mirror
  
• D. Diverging mirror

Answer 1

The correct option is C Concave mirror

• Concave mirrors are used to obtain an enlarged image of these organs. Diverging mirror or convex mirror diverges the light rays falling on it and the image appears diminished, which do not help in close inspection of the organs. Plane mirror obtains the image as same size of the object and hence does not serve the purpose.
• Concave mirrors are used for many purposes. Doctors use concave mirrors for examining eyes, ears, nose and throat. Concave mirrors are also used by dentists to see an enlarged image of the teeth.
