Refraction through glass slab #Shorts

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

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