Question

A child is standing in front of a magic mirror. She finds the image of her head bigger, the middle portion of her body of the same size and that of the legs smaller. The following is the order of combinations for the magic mirror from the top:

• A. Plane, convex and concave
• B. Convex, concave and plane
• C. Concave, plane and convex
• D. Convex, plane and concave

Hint:

Remember the unique identifying feature of each mirror for close objects:
- Enlarged \(\to\) Concave mirror
- Same size \(\to\) Plane mirror
- Diminished \(\to\) Convex mirror

Answer 1

The Correct Option is C

Step 1: Look at what the head tells us.
The head appears bigger than normal, and a magnified, upright image close to the mirror is the signature of a concave mirror, so the top section must be concave.
Step 2: Look at the middle of the body.
The middle portion looks exactly the same size as the real body, and only a plane mirror always gives a same size, upright image regardless of distance, so the middle strip is a plane mirror.
Step 3: Look at the legs.
The legs look smaller than they really are, and a convex mirror is the only type that always produces a diminished, upright image, so the bottom strip is convex.
Step 4: Read the order from top to bottom.
Putting the sections together in the order we identified them gives concave first, then plane, then convex.
\[ \boxed{\text{Concave, Plane and Convex}} \]
