When unpolarized light passes through a polarizer, it gets polarized. Suppose that a polarizer is placed in front of an unpolarized light source, and the intensity of the source is 100 W/m². If the intensity of the light that passes through the polarizer is 50 W/m², what is the angle between the transmission axis of the polarizer and the direction of polarization of the incident light?
