Unpolarized white light is incident on a polarizer and then falls on an analyzer whose TA (Transmission Axis) makes an angle of = 16.9 with the polarizer. What is the fraction of the original light transmitted through both the polarizer and analyzer?

If the analyzer is rotated until the transmitted intensity is 33.1 percent of the original light intensity, what is the new angle of the analyzer with respect to the polarizer? Answer in units of .
