Unpolarized light of intensity I0 passes through four ideal polarizing sheets. The polarizing angle of each sheet is rotated 30° from the one before it, so that the last sheet is aligned at 90° to the first sheet
What is the intensity of the light emerging from the fourth sheet in terms of I0?
0.21 I0
