A ray of light travelling in a medium of refractive index μ is incident at an angle θ on a composite transparent plate consisting of 50 plates of refractive indices 1.01 μ , 1.02 μ , 1.03 μ … ..1.50 μ

Question

A ray of light travelling in a medium of refractive index $μ$ is incident at an angle $θ$ on a composite transparent plate consisting of 50 plates of refractive indices $1.01 μ, 1.02 μ, 1.03 μ \dots ..1.50 μ$ . The ray emerges from the composite plate into a medium of refractive index $1.6 μ$ at angle x . Then

Options:

Answer:

B

Solution:

Snell's law

$μ sin θ = 1.6 μ sin x$

$sin x = \frac{5}{8} sin θ$
