Irradiances of polarized and unpolarized beams

  1. May 19, 2012 #1
    1. The problem statement, all variables and given/known data
    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 irradiances of the polarized and unpolarized beams?


    2. Relevant equations



    3. The attempt at a solution
    i got the ratio as 1. can u verify my answer?

    Step 1: find V
    Step 2: equate that to the ratio of Ip/(Ip+Iu)
