A beam of initially unpolarized light passes through a sequence of three ideal polarizers. The angle between the axes of the first and second polarizers is 18.1 degree , and the angle between the axes of the second and third polarizers is 52.9 degree . What is the ratio of the intensity of light emerging from the third polarizer, I3, to the intensity of light incident on the first polarizer, I0? I3/I0 =
