Equation for critical angle

WebOct 29, 2015 · When the ray strikes the internal side of the pavilion, it will be refracted and lost if the angle of incidence it forms with the normal to the the facet is less than the critical angle. For quartz, the critical angle is sin -1 (1 / 1.54) = sin -1 (.649351) = 40.49°. In this case the pavilion facets are cut at 35°.
