Light of wavelength 700 nm is incident on the face of a fused quartz prism at an angle of 75.0° (with respect to the normal to the surface). The apex angle of the prism is 60.0°. Use the value of n from Figure 35.20 and calculate the angle
(a) Of refraction at this first surface,
(b) Of incidence at the second surface,
(c) Of refraction at the second surface, and
(d) Between the incident and emerging rays.
