defined as the angle between the plane-of-vibration and the plane-of-incidence. Thus for linearly polarized light,

Figure P.4.67 is a plot of γr versus θi, for internal and external reflection at an air-glass interface (nga = 1.51), where γt = 45°. Verify a few of the points on the curves and in addition show that
