GLASS: n = 1.5 INCIDENT RAY 15. In the figure shown on the right, which ray represents the refracted beam of light? Use the multiple choices labeled on the diagram. 16. Glass has an approximate index of refraction = ng A 1.5. Diamond, however, B has an index of refraction WATER: n=1.33 na = 2.4. A) The speed of light is the same through either medium, c = 3 x 108m. The index of refraction does not matter. The speed of light is slower through glass because its index is smaller. B) C) The speed of light is slower through diamond. The higher the index of refraction, the slower the medium. You cannot say for sure which medium is faster; it will depend on the color of the glass. D) 17. The index of refraction of the human cornea is n = 1.38. What is the speed of light passing through this medium? A) v = 1.69 x 108m D) v = 2.41 x 108m B) v = 1.93 x 108m E) v = 2.65 x 108m C) v = 2.17 x 108m F) v = 3.00 x 108m
