In a museum, a boy stands in front of a mirror and finds that his image has a big head, normal body and small legs. This is because the mirror is made up of three different mirrors arranged from the top to boom as:
1. Plane mirror, concave mirror, convex mirror
2. Concave mirror, convex mirror, plane mirror
3. Concave mirror, plane mirror, convex mirror
4. Convex mirror, concave mirror, plane mirror

Best answer
Correct Answer - Option 3 : Concave mirror, plane mirror, convex mirror

CONCEPT:

Mirror

  • A mirror is a polished surface that reflects the light incident on it.
  • Types of the mirror:
    1. Plane mirror
    2. Spherical mirror
      • ​​Concave mirror
      • Convex mirror

EXPLANATION:
 

Plane mirror

​​Concave mirror

Convex mirror

The plane mirror always formed the image equal to the size of the object irrespective of the position of the object. The concave mirror formed an image bigger than the object when the object is placed between the focus and the pole. The convex mirror always formed the image smaller than the object irrespective of the position of the object.
  • All three mirrors are of a different type.
  • The first mirror will be a concave mirror because the image is bigger.
  • The second mirror will be a plane mirror because the image is normal.
  • The third mirror will be a convex mirror because the image is small.
  • Hence, option 3 is correct.
