The refraction indices of materials vary slightly with temperature and with the wavelength of the light going through the material. The index of refraction of water at 70°C for a helium neon laser is 1.32 (use the fraction-no calculators). If the laser shone through a right triangular prism of water (held by in place by negligibly thin walls) as drawn, a) What is the critical value of the angle of incidence, 8₁, such that beyond this angle, the laser is not transmitted through the far side as indicated? 8₂
