Diamond index of refraction
WebFigure 1.14 (a) A ray of light crosses a boundary where the index of refraction decreases. That is, n 2 < n 1. The ray bends away from the perpendicular. (b) The critical angle θ c is the angle of incidence for which the angle of refraction is 90 °. (c) Total internal reflection occurs when the incident angle is greater than the critical angle.

WebTotal internal reflection, coupled with a large index of refraction, explains why diamonds sparkle more than other materials. The critical angle for a diamond-to-air surface is only 24.4º, and so when light enters a diamond, it has trouble getting back out. (See Figure 7.) Although light freely enters the diamond, it can exit only if it makes ...
WebAgain the index of refraction for air is taken to be n 1 = 1.00, and we are given θ 1 = 30.0º. We can look up the index of refraction for diamond in Table 1, finding n 2 = 2.419. The only unknown in Snell’s law is θ 2, which we wish to determine. Solution Solving Snell’s law for sin θ 2 yields
