Answer:
Angle of incidence=Angle between incident ray and normal=60 degree
The angle which the refracted ray makes with the normal on the first face of slab=Angle of refraction=42 degree
Since the normals drawn on both the faces of slab are parallel,
So alternate angles are equal and hence the angle between refracted ray and the normal drawn on the second face will be equal to the angle of refraction = 42degree
And in case of glass slab,angle of incidence is always equal to angle of emergence.
Hence,
Angle of emergence=60 degree
