Diagram (a) and (b) in figure below show the refraction of a ray of light of single colour through a prism and a parallel sided glass slab respectively.

(i) In each diagram, label the incident, refracted, emergent rays and the angle of deviation.
(ii) In what way the direction of the emergent ray in the two cases differ with respect to the incident ray ? explain your answer.
