You may have polarized sunglasses that eliminate glare by polarizing the light. When light is polarized, all of the waves are traveling in parallel planes. Suppose horizontally-polarized light with intensity I0 strikes a polarizing filter with its axis at an angle of with the horizontal. The intensity of the transmitted light It and are related by the equation cos I _t I0 . If one fourth of the polarized light is transmitted through the lens, what angle does the transmission axis of the filter make with the horizontal? 60
