In the figure, unpolarized light is sent into a system of five polarizing sheets. Their polarizing directions, measured counterclockwise from the positive direction of the y axis, are the following:sheet 1: 0°sheet 2: [th1]°sheet 3: [th2]°sheet 4: [th1]°sheet 5: 90° What percentage of the initial intensity is transmitted by the system?
