1. The problem statement, all variables and given/known data Unpolarized light of intensitry 3 W/m^2 goes through two polarizing films. Their axes are 60 degrees apart. What is the intensity of light transimitted by the second film 2. Relevant equations ##I_2 = I_1*cos^2 phi## Where I_1 is the intensity of light after going through the first film and I_2 is the intensity of light after going through the second film. I also read online that the intensity of light going through one polarized lens is one half the original intensity, I don't know if I should use that since we never learned it in class and its not in the lab manual 3. The attempt at a solution I don't know whether to just use the first equation and plug the 3W/m^2 in for I_1, or to use both equations(use half of 3 W/m^2 as I_1), which I don't think their expect since I was only given the first equation.
