Light of wavelength 700 nm is incident on the face of a fused quartz prism (n = 1.458 at 700 nm) at an incidence angle of 72.4°. The apex angle of the prism is 60.0°.
(a) Calculate the angle of refraction at the first surface.
(b) Calculate the angle of incidence at the second surface.
(c) Calculate the angle of refraction at the second surface.
(d) Calculate the angle between the incident and emerging rays.
