a. Polarized light is incident on 4 polarizing sheets. The axis of the first polarized sheet makes an angle with the plane of polarization.

a. Polarized light is incident on 4 polarizing sheets. The axis of the first polarized sheet makes an angle θ with the plane of polarization. Each subsequent sheet has an axis that is rotated by an angle θ from that of adjacent sheets. Find θ if 14% 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 80°, but you do not want the final intensity to be less than 51% of the initial intensity. What is the minimum number of polarizing sheets you must use …………..?
