The transmitted inLight from a source passes through two polarizers whose axes are perpendicular (crossed). The intensity after Unpolarized light of intensity $I_0$ passes through three polarizers in succession. The axis of the second makTwo polaroids are kept with their polarising axes parallel; the transmitted intensity is $I$. One polaroid is
