A ray of light travelling in air is incident at grazing incidence on a slab with variable refractive index, n (y) = [ky^(3//2) + 1 ]^(1//2) where k=1 m^(-3//2) and follows path as shown in the figure. What is the total deviation produced by slab when the ray comes out.

Light guidance in an optical fibre can be understood by considering a structure comprising of thin solid glass cylinder of refractive index n_1 surrounded by a medium of lower refractive index n_2 . The light guidance in the structure takes place due to successive total internal reflectrions at the interface of the media n_1 and n_2 as shown in the fugure. All rays with the angle of incidence i less than a particular value i_m are confined in the medium of refractive index n_1 . The numerical aprture (NA) of the structure is defined as sini_m For two structure namely S_1 with n_1=(sqrt45)/(4) and n_2=(3)/(2) , and S_2 with n_1=(8)/(5) and n_2=(7)/(5) and taking the refractive index of water to be (4)/(3) and that of air to be 1, the correct option (s) is (are) ?
