    Irradiances of polarized and unpolarized beams

    Homework Statement A beam of light is composed of a mixture of unpolarized and linearly polarized waves. The beam is analyzed with a polarizer. As the transmission axis is rotated, the transmitted irradiance varies from a maximum I[max] to a minimum of 1/3 I[max]. What is the ratio of the...
