Answer: A light ray travels from vacuum into a slab of
Chapter 35, Problem 11(choose chapter or problem)
A light ray travels from vacuum into a slab of material with index of refraction n1 at incident angle u with respect to the surface. It subsequently passes into a second slab of material with index of refraction n2 before passing back into vacuum again. The surfaces of the different materials are all parallel to one another. As the light exits the second slab, what can be said of the final angle f that the outgoing light makes with the normal? (a) f . u (b) f , u (c) f 5 u (d) The angle depends on the magnitudes of n1 and n2. (e) The angle depends on the wavelength of the light.
