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

Answer 1

(D)

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