A system of three polarizing sheets intercept a beam of initially unpolarized light. The polarizing direction of the first sheet is parallel to the y- axis, that of the second sheet is at an angle of T counterclockwise from the y-axis and that of the third sheet is parallel to the x-axis. The inten- sity of light emerging from the three-sheet system is 11.52% of the original intensity I0 . Determine the angle T . In which direction is the emerging light polarized?

Solution:
A system of three polarizing sheets intercept a beam of initially unpolarized li
