Suppose you need to rotate the plane of polarization of a plane-polarized beam of light by 90 degrees and produce only a 10% loss in intensity, using polarizers. Let N be the number of polarizers and theta be the (same) angle between successive polarizers. Find the number of polarizers N. Find the angle between the successive polarizers.
