Multiple choice

A person standing in from of a mirror finds his image thinner but with normal height. The Mirror in question is-

  1. Concave and spherical

  2. Convex and spherical

  3. Convex and cylindrical with axis vertical

  4. Convex and cylindrical with axis horizontal

C Correct answer
Explanation

A convex cylindrical mirror with its axis vertical produces an image that is thinner (compressed horizontally) but maintains normal height (no vertical distortion). The curvature along one axis only causes compression in that direction. A concave mirror magnifies, convex spherical compresses in all directions, and horizontal-axis cylinder would compress height.
