Refraction Through Glass Slab

Prove that the angle of emergence and angle of incidence are equal in case of refraction through a glass slab

In the given figure, a wavefront AB moving in air is incident on a plane glass surface XY, Its position CD after refraction through a glass slab is showin in gigure. The ratio of width of wavefront AB to the refracted wavefront CD is

In the adjoining figure, a wavefront AB moving in air is incident on a plane glass surface XY. Its position CD, after refraction through a glass slab is shown also along with the normals drawn at A and D. The refractive index of glass with respect to air will be equal to
