A transparent slab of thickness d has a refractive index n(z) that increases with z. Here z is the vertical distance inside the slab, measured from the top. The slab is placed between two media with uniform refractive indices n1 and n2 (> n1), as shown in the figure. A ray of light is incident with angle θi, from medium 1 and emerges in medium 2 with refraction angle θt with a lateral displacement l.
Which of the following statement(s) is(are) true?
  • a)
    n1 sinθi = n2 sinθf
  • b)
    n1 sin θi = (n2 – n1) sinθf
  • c)
    l is independent of n2
  • d)
    l is dependent on n(z)
Correct answer is option 'A,C,D'. Can you explain this answer?

n1 sin θi = n2 sinθf [∵ 1 and 2 interfaces are parallel] l depends on the refractive index of transparent slab but not on n2 . In fact θf depends on n2.
