In experiment 1, unpolarized light falls on the polarizer in the figure. The angle of the polarizer is = 58.0°. In experiment 2, the unpolarized light is replaced by light of the same intensity, but the light is polarized along the direction of the polarizer's transmission axis. (a) By how many additional degrees must the analyzer be rotated, so the light falling on the photocell has the same intensity as it did in experiment 1? (b) Is (1) increased or (2) decreased by this addition rotation? Give the number of the correct choice.
