When a light passes through prism, it bends towards the base of prism.
In refraction of light through a prism, the light ray:
(a) suffers refraction only at one face of the prism
(b) emerges out from the prism in a direction parallel to the incident ray
(c) bends at both the surfaces of prism towards its base
(d) bends at both the surfaces of prism opposite to its base
