Question 2 1 pts A slab of material I rests on the sarface of a slab of material 2 . A light ray in material 1 has an angle of incidence of
30\deg
on the interface between the matrrials, while the ray in material 2 has an angle of refraction of
45\deg
. What is the critical angle of incidence for neal intemal reflection for a my of light going from material 2 to material 1 ?
q,
In this case there is no critical angle.
45\deg

30\deg
At least one of the indices of refraction of its equivalent in meoded to solve this problem.
