Geometrical Optics question

2016 · Shift 1 · Q48

JEE AdvancedPhysicsGeometrical OpticsMultiple correct+4 / −2
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 θ\thetaθ i from medium 1 and emerges in medium 2 with refraction angle θ\thetaθ f with a lateral displacement lll. JEE Advanced 2016 Paper 1 Offline Physics - Geometrical Optics Question 50 English Which of the following statement(s) is (are) true?
  1. A

  2. B
    n1 sin θ\thetaθ i = (n2 −-− n1) sin θ\thetaθ f
  3. C
    n1 sin θ\thetaθ i = n2 sin θ\thetaθ f
  4. D
    lll is independent of n2
