55. We label the light ray’s point of entry A, the vertex of the prism B, and the light ray’s exit point C. Also, the point in Fig. 33-57 where ψis defined (at the point of intersection of the extrapolations of the incident and emergent rays) is denoted D. The angle indicated by ADCis the supplement of , so we denote it s= 180° – . The angle of refraction in the glass is θ21=nsin . The angles between the interior ray and the nearby surfaces is the complement of 2, so we denote it
