A thin bi-convex lens made out of a material of refractive index μ 1 is placed in a medium of refractive index μ 2 . A paraxial beam of light, parallel to the principal axis of the lens, is shown in the figure. Based on the ray diagram, we can conclude that

Options

  1. Aμ 1 > μ 2
  2. Bμ 1 ≤ μ 2
  3. Cμ 1 = μ 2
  4. D&#x3BC; 1 < &#x3BC; 2

Correct answer

D. &#x3BC; 1 < &#x3BC; 2

Step-by-step solution

A bi-convex lens acts as a diverging lens when it is placed in a denser medium.
