Question

A student carries out the experiment of tracing the path of a ray of light through a rectangular glass slab at different angle of incidence , ∠i = 30 o and ∠i = 45 o . In the two cases the student is likely to observe the set of values of angle of refraction and angle of emergence as​

Answer 1

According to the law of refraction angle of incidence will be equal to angle of emergence

therefore angle of emergence will be 30

and in second case it will be 45
