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. 3357 where
ψ
is defined (at the point of intersection
of the extrapolations of the incident and emergent rays) is denoted
D
. The angle indicated
by
ADC
is the supplement of
, so we denote it
s
= 180° –
. The angle of refraction in
the glass is
θ
2
1
=
n
sin . The angles between the interior ray and the nearby surfaces is the
complement of
