A boy is standing in front of and close to a special mirror. He finds the image of his head bigger than normal, the middle part of his body of the same size, and his legs smaller than normal. The special mirror is made up of three types of mirrors in the following order from top downwards:- Convex, Plane, Concave
- Plane, Convex, Concave
- Concave, Plane, Convex
- Convex, Concave, Plane
(c) Concave, Plane, Convex
Explanation
The order of the special mirror (made up of three types of mirrors), from top to downwards is:
1. A concave mirror - forms an image larger than the object.
2. A plane mirror - always forms an image similar to the size of the object.
3. A convex mirror - always forms an image smaller than the object.
Thus, when the boy finds the image of his head bigger than normal, then it means the mirror is a concave mirror.
When he finds the middle part of his body of the same size, then it means the mirror is a plane mirror.
And, when he finds his legs smaller than normal, then it means the mirror is a convex mirror.
