A student performs an experiment with glass slab to trace the path of a ray of light entering from air into glass slab and emerging into air again. On looking carefully at the trace obtained on paper, he will observe that the emergent ray and the incident ray:(1) are converging (coming closer to each other)(2) are diverging (moving away from each other)(3) are perpendicular (at right angles to each other)(4) are parallel (at equidistant from each other)

1.	A student performs an experiment with glass slab to trace the path of a ray of light entering from air into glass slab and emerging into air again. On looking carefully at the trace obtained on paper, he will observe that the emergent ray and the incident ray:(1) are converging (coming closer to each other)(2) are diverging (moving away from each other)(3) are perpendicular (at right angles to each other)(4) are parallel (at equidistant from each other)
