From within a diamond, a light ray is incident on the interface
between diamond (nD = 2.4) and air. What is the critical
angle for total internal reflection?
FYI: the small value for tangentC implies that light is
easily 'trapped' within a diamond, and eventually emerges after
many internal reflections.
A: 24.6 degrees

15 Diamond has an index of refraction of 2.42, and part of the reason diamonds sparkle is that this encourages a light ray to undergo many total internal reflections before it emerges. (a) Cal culate the critical angle at which total internal reflection occurs in diamond. (b) Explain the interpretation of your result: Is it mea- sured from the normal, or from the surface? Is it a minimum angle for total internal reflection, or is it a maximum? How would...

Consider the case of light incident from air (or vacuum) on a planar interface with diamond. Calculate, (a) the reflection and transmission coefficients at normal incidence. (b) the reflection and transmission coefficients at the Brewster angle. (c) the “crossover” angle where the transmission and reflection coefficients are equal. Referring back to part (b), we might have imagined that, as the reflection coefficient is zero at Brewster's angle, that the transmission coefficient would equal one. But as your answer should have...
