Angle of deviation in refraction of light through a glass prism is the :
- (a)Angle between the normal at the face on the emerging side of the prism and the emergent ray.
- (b)Angle between the normal at the face on the emerging side of the prism and the incident ray.
- (c)Angle between the incident ray and the refracted ray.
- (d)Angle between the directions of incident ray and emergent ray.
