Two identical objects are placed in front of convex mirror and concave mirror having same radii of curvature of 12 cm , at same distance of 18 cm from the respective mirrors. The ratio of sizes of the images formed by convex mirror and by concave mirror is :

Options

  1. A1 / 2
  2. B2
  3. C3
  4. D1 / 3

Correct answer

A. 1 / 2

Step-by-step solution

aligned & Using m= f u-f & m₁= 6 18-6 = 1 2 aligned m ₂= 6 18+6 = 1 4 ~m ₂ ~m ₁ = 1 2
