Question

If we want to see our full image then the minim um size of the plane mirror:

• A. Should be twice of our height
• B. Should be of our height
• C. Should be half of our height
• D. Depends upon our distance from mirror

Answer 1

The correct option is C Should be half of our height

The minimum mirror height required to see our whole body in a mirror oriented in parallel to our body is half the height of our body. The top edge of the mirror should be half in-between the level of our eyes and the top of our head, and the bottom edge of the mirror should be at a level half way between our eyes and our feet. This is independent of our distance to the mirror.
