A light ray goes through two thick rectangular slabs of glass, each of the same uniform thickness. The first slab has index of refraction $n_1$ and the second $n_2.$ If ${}_i{}_f{n}_1,$ how does the original angle $of$ incidence ${}_i$ into the first slab compare $to$ the final angle $of$ refrsction ${}_f$ where the ray leaves the second slab going back into air?
