If the light is unpolarized, I won't have just three angles, but all the angles between 0 and 2 π, so the sum turns an integral: I = I 0 ∫ 0 2 π cos 2 ( θ) d θ. However, it seems that, instead of that integral, I should use the average value, i.e. the integral divided by 2 π. Why? polarization Share
