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 is shone through a right triangular prism of water (held by in place by negligibly thin walls) as drawn, 8. What is the critical value of the angle of incidence, ;, such that beyond this angle, the laser is not transmitted through the far side as indicated? 9. Does total internal reflection occur for incident angles greater than or less than ec?
