Chapter 32, Problem 45P
(II) The block of glass (n = 1.5) shown in cross section in Fig. 32–51 is surrounded by air. A ray of light enters the block at its left-hand face with incident angle θ1 and reemerges into the air from the right-hand face directed parallel to the block’s base. Determine θ1.

Suppose a ray strikes the left face of the prism in Fig. 23–64
at 45.0° as shown, but is totally internally reflected at the
opposite side. If the apex angle (at the top) is 0 = 65.0°,
what can you say about the index of refraction of the prism?
(II) An aquarium filled with water has flat glass sides whose
index of refraction is 1.54. A beam of light from outside
the aquarium strikes the glass at a 43.5° angle to the
perpendicular (Fig. 23–56). What is the angle of this light
ray when it enters (a) the glass, and
then (b) the water? (c) What would be
the refracted angle if the ray entered
the water directly?
