- 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.

An optical cable in air is orientated horizontally. The cable has a core and a cladding layer. The index of refraction
for the core is 1.3 and the index of refraction for the cladding layer is 1.2. A light ray enters the center of the cable
with an incident angle ß=58°. The ray is subsequently refracted at the core-cladding interface and the cladding-air
interface. The angle between the exit ray and the cable wall is a. What is the angle a? The index of refraction of air
is 1.
