Why is the following situation impossible? A laser beam strikes one end of a slab of material of length L = 42.0 cm and thickness t = 3.10 mm as shown in the figure below (not to scale). It enters the material at the center of the left end, striking it at an angle of incidence of 8 = 50.0°. The index of refraction of the slab is n = 1.48. The light makes 85 internal reflections from the top and bottom of the slab before exiting at the other end. L n
