μ = 1.20 + \(\frac{8\times10^5}{λ^2}\)
λ is wave - length of incident light.
AB is a ray of λ = 400 nm while ray CD has λ = 500 nm. The two rays are incident as shown in Fig. Which of the following statements is correct?
(1) Both rays AB and CD, emerge out of face PR
(2) Ray AB does not emerge out, but ray CD emerges out, from face PR
(3) Ray AB emerges out, but ray CD does not emerge out of face PR
(4) Neither ray AB nor ray CD, emerges out of face PR
