Question

what is relation in the following
pls give reason as well​

Answer 1

hey bro

as you can see in this diagram

when the light enters in medium 1 it doesn't refracts and when it passes through medium 2 it is same as before so, refractive index of medium 1 = refractive index of medium 2.

and when it passes through medium 3 it gets deviated . so medium 2 has lesser refrective index than medium 3.

option c is correct .
