Question

In what way the direction of emergent ray in a prism and a rectangular glass slab differ with respect to the incident ray?Explain.

Answer 1

Howdy!!

your answer is ----

♦ In rectangular glass slab , the emergent ray is Parallel to the incident ray because the opposite side of rectangular slab is parallel .

♦ in a prism the opposite side is no parallel due to this emergent ray is not parallel to incident ray and also incident ray diverge toward prism base .



hope it help you

Answer 2

In prism, the emergent ray gets deviated towards the base of the prism .

In rectangular glass slab,the emergent will be parallel to the incident ray.
