Question
A parallel beam of light composed of a red and a green light ray is incident obliquely at a point on the face of a rectangular glass slab. When coming out from the opposite parallel face, the red and the green light rays emerges

Solution
The correct option is B parallel to each other
The red and the green rays being the part of the parallel beam, they will regain their original direction after two successive refractions from the surfaces of the glass slab. There will be only lateral shift.
Thus, they will emerge parallel to each other.
Why this question?
Tips: Always remember that a glass slab produces lateral shift to the incident ray.
