You use a sequence of ideal polarizing filters, each with its axis making the same angle with the axis of the previous filter, to rotate the plane of polarization of a polarized light beam by a total of 45.0°. You wish to have an intensity reduction no larger than 14.4%.
(a) How many polarizers do you need to achieve your goal? ........... (b) What is the angle between adjacent polarizers? .......... °
