Laser light is passed through a rod made out of a material with an index of refraction of 1.62, a length L = 45.0 cm, and square cross section of length h = 3.00 mm on a side as shown in the figure. If the light enters at the center of the rod with an angle of incidence in air of 0₁ = 49.7°, determine the numb of total internal reflections before it emerges from the opposite end of the rod. 42.0 cm 3.10 mm
