A ray of light is incident on a glass slab at grazing incidence. The refractive index of the material of the slab is given by mu =sqrt(1+sqrty) . If the thickness of the slab is d, determine the equation ofthe trajectory of the ray inside the slab and the coordinates of the point where the ray exits from the slab. Take the origin to be at the point of entry of the ray.
