(A) Draw a ray diagram to show the refraction of a ray of light passing through an equilateral glass prism. Mark the angle through which the emergent ray bends from the direction of the incident ray and also name it.
Solution
(A)
[Diagram of a triangular prism showing incident ray, refraction at both faces, emergent ray, and the angle of deviation D marked between the incident ray extended and the emergent ray]
(one mark for diagram and ½ for labelling.)
Angle of deviation
