The diagrams (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. (a)

The diagrams (a) and (b) show the refraction of a ray of light of single colour through a prism and a parallel sided glass slab, respectively. In each diagram, label the incident, refracted, emergent rays and the angle of deviation. In what way the direction of emergent ray in the two cases differ with respect to the incident ray? Explain your answer. Refraction of light at plane surfaces, Concise Physics Class 10 Solutions.

(b)

(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.

(i) The below diagram shows the refraction of a ray of light of single colour through a prism with the incident, refracted, emergent rays and the angle of deviation properly labelled:

The below diagram shows the refraction of a ray of light of single colour through a parallel sided glass slab with the incident, refracted, emergent rays and the angle of deviation properly labelled:

(ii) In a prism, the refraction of light occurs at two inclined faces, so the emergent ray is not parallel to the incident ray but it is deviated towards the base of the prism. On the other hand, in a parallel sided glass slab, the refraction of light occurs at two parallel faces, so the emergent ray is parallel to the incident ray with a lateral displacement.
