Question

Diagrams (a) and (b) in Fig. 4.34 below show
the refraction of a ray of light of single colour
through a prism and a parallel sided glass slab
respectively
(b)
Fig. 4.34
(1) In each diagram, label the incident, refracted.
emergent rays and the angle of deviation.
(11) In what way the direction of the emergent ray in
the two cases differ with respect to the incident
ray ? Explain your answer.​
