प्रश्न
Light passes through a rectangular glass slab and through a triangular glass prism. In what way does the direction of the two emergent beams differ and why?

उत्तर
In case of a rectangular glass slab, emergent rays of light are always parallel to the direction of incident rays.
When a light ray passes through a prism, it bends towards the base of the prism. Hence, incident ray and emergent ray are not parallel to each other as they are in case of a glass slab.
