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 Figure P34.36 (not to scale). It enters the material at the center of the left end, striking it at an angle of incidence of 0 = 50.0°. The index of refraction of the slab is n = 1.48. The light makes 85 inter- nal reflections from the top and bottom of the slab before exiting at the other end. 0 L n
