A student traces the path of a ray of light through a glass prism for different angles of incidence. He analysis each diagram and draws the following conclusion:
I. On entering prism, the light ray bends towards its base.
II. Light ray suffers refraction at the point of incidence and point of emergence while passing through the prism.
II. Emergent ray bends at certain angle to the direction of the incident ray.
IV. While emerging from the prism, the light ray bends towards the vertex of the prism.
Out of the above inferences, the correct ones are:
(a) I, II and III
(b) I, III and IV
c) II, III and IV
(d) I and IV
