Question
8 CE Predict/Explain Consider the two polarization experi- ments shown in Figure 25-28. (a) If the incident light is unpolar- ized, is the transmitted intensity in case A greater than, less than, ransmitted intensity in case B2 (b) Choose the 72 or the same as the t t explanation from among the following: I. T he transmitted intensity is the same in either case; the first polarizer lets through one-half the incident intensity, and the second polarizer is at an angle relative to the first. II. Case A has a smaller transmitted intensity than case B be- cause the first polarizer is at an angle relative to the inci- dent beam. III. Case B has a smaller transmitted intensity than case A be- cause the direction of polarization is rotated by an angle in the clockwise direction in case B.

Explanation / Answer
polarization by transmission
option 1 is correct
The transmitted intensity is same in either case.
The first polarizer lets through one half the incident intensity, and the second polarizer is at angle relative the first one. both haveing same intensity.
