A.) Polarized light is incident on 5 polarizing sheets. The axis of the first polarized sheet makes an angle with the plane of polarization. Each subsequent sheet has an axis that is rotated by an angle from that of adjacent sheets. Find if 40% of the incident intensity is transmitted by the sheets. B.) Suppose you want to rotate the plane of polarization of a beam of polarized light by 82°, but you do not want the final intensity to be less than 57% of the initial intensity. What is the minimum number of polarizing sheets you must use? Assume that each sheet is rotated the same angle relative to the adjacent sheets. sheets
