A ray of light passes through four transparent media with refractive indices μ123 and u4 as shown in Fig. The surfaces of all media are parallel. If the emergent ray CD is parallel to the incident ray AB, we must have
  • a)
    μ1 = μ2
  • b)
    μ2 = μ3
  • c)
    μ3 = μ4
  • d)
    μ4 = μ1
Correct answer is option 'D'. Can you explain this answer?
