Question

Select from the following the best experimental set-up for tracing the path of a ray of light passing through a rectangular glass slab : (a) P (b) Q (C) R (d) S

Answer 1

Answer:

q

Explanation:

iin pqrs this letter will represent the most

Answer 2

Answer:

correct option is d: S

Explanation:

please refer the attachment for diagram. As question is incomplete

Refraction through glass slab :

When a ray of light passes through glass slab it undergoes refraction from rarer to denser medium so it bends towards the normal. Then the light ray on striking the other surface of glass undergoes refraction from denser to rarer medium so bends away from normal.

so based on angle if incident in figure S, we can make out it is the correct form of experimental setup
