Chapter 25, Problem 69PCE
Predict/Explain Consider the two polarization experiments shown in Figure 25-42. (a) If the incident light is polarized in the horizontal direction, is the transmitted intensity in case A greater than less than or the same as the transmitted intensity in case B? (b) Choose the best explanation from among the following:
- I. I The two cases have the same transmitted intensity because the angle between the polarizers is θ in each case
- II. The transmitted intensity is greater in case B because all of the initial beam gets through the first polarizer
- III. The transmitted intensity in case B is smaller than in case A, in fact, the transmitted intensity in case B is zero because the first polarizer is oriented vertically.
