Suppose the incident beam of light islinearly polarized in the vertical direction. In addition, the transmission axis of the analyzer is at an angle of 80.0° to the vertical.What angle should the transmission axis of the polarizer makewith the vertical if the transmitted intensity is to be a maximum?
Unpolarized light passes through two polarizers whose transmission axes are at an angle of 40.0 ∘with respect to each other. What fraction of the incident intensity is transmitted through the polarizers?
Polarized light is incident on 7 polarizing sheets. the axis of the first polarized sheet makes an agle theta with the plane of polarization. each subsequent sheet has an axis that is rotated by an angle theta from that of adjacent sheets. find theta if 91% of the incident intensity is transmitted by the sheets.
