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 θ\theta i into the first slab compare to the final angle of refraction θ\theta f where the ray leaves the second slab going back into air?
