Un-polarized light is incident on a system of three polarizers. The second polarizer is oriented at an angle of 30.0° with respect to the first and the third is oriented at an angle of 45.0° with respect to the first. If the light that emerges from the system has an intensity of 23.0 W/m2, what is the intensity of the incident light?
