13. A beam of light composed of red and green rays is incident obliquely at a point on the face of rectangular glass slab. When coming out on the opposite parallel face, the red and green rays emerge from
[2004]
(a) one point propagating in the same direction
(b) two points propagating in two different non-parallel directions
(c) two points propagating in two different parallel directions
(d) one point propagating in two different directions
