Why is the following situation impossible? A laser beam
Chapter 35, Problem 66(choose chapter or problem)
Why is the following situation impossible? A laser beam strikes one end of a slab of material of length L 5 42.0 cm and thickness t 5 3.10 mm as shown in Figure P35.66 (not to scale). It enters the material at the center of the left end, striking it at an angle of incidence of u 5 50.0. The index of refraction of the slab is n 5 1.48. The light makes 85 internal reflections from the top and bottom of the slab before exiting at the other end.
