Answer:
The minimum refractive index of the right prism is 1.414 i.e. option (c)
Explanation:
Since this is a right prism, the other two angles are 30 and 60
We know that B>>A
This is an example of total internal reflection.
therefore, i (a) > i (b) >>>>>>>> (angle of incidence = i )
i(b) max = 45
(c) ...... (critical angle)
(c) 45
1/ u = 1 /
thus, the refractive index is u=
