A ray of light travelling in air is incident on a composite transparent slab at an angle of incidence `i = 45°`. The composite slab consist of 100 parallel faced slices of equal thickness. The refractive index of the `n^(th)` slice (counting from the one on which light is incident) is given by `mu_(n) = 1.0 + 0.01n`. The medium on the other side of the slab has refractive index of `sqrt(2)` . Calculate the angular deviation suffered by the ray as it comes out of the slab.
