Concept

Problem: Unpolarized light with intensity I0 is incident to two polarizing filters. The axis of the first filter is oriented at 37.0° counterclockwise from the horizontal, as shown in the sketch. The axis of the second filter is vertical. If the intensity of the light after it has passed through both filters is 0.300 W/m2, what is the initial intensity I0 of the light?
