A Light Ray Goes Through Two Thick Rectangular Slabs of Glass,each

question 25

Multiple Choice

A light ray goes through two thick rectangular slabs of glass,each of the same uniform thickness.The first slab has index of refraction n₁ and the second n₂.If n₁ < n₂.How does the original angle of incidence $\theta$ _i into the first slab compare to the final angle of refraction $\theta$ _f where the ray leaves the second slab going back into air? $A light ray goes through two thick rectangular slabs of glass,each of the same uniform thickness.The first slab has index of refraction n1 and the second n2.If n1 < n2.How does the original angle of incidence \theta i into the first slab compare to the final angle of refraction \theta f where the ray leaves the second slab going back into air?
