74. Since some of the angles in Fig. 33-70 are measured from vertical axes and some are measured from horizontal axes, we must be very careful in taking differences. For instance, the angle difference between the first polarizer struck by the light and the second is 110º (or 70º depending on how we measure it; it does not matter in the final result whether we put θ 1 = 70º or put 1 = 110º). Similarly, the angle difference between the second and the third is
