Question
In an experiment to trace the path of a ray of light through a glass prism for different values of angle of incidence a student would find that the emergent ray:
(A) is parallel to the incident ray
(B) perpendicular to the incident ray
(C) is parallel to the refracted ray
(D) bends at an angle to the direction of incident ray

Solution
(D)
As the light gets refracted two times at different angles, the emergent ray bends at an angle to the direction of incident ray.
