Question

In a lab experiment, a student sets up two polarizers along an optical rail. A light is incident on one of the polarizers, and the transmission axis of the polarizers are at 90° to each other, so no light passes through them. Next, the student places a third polarizer in between the first two, so that its transmission axis is at an angle of ? = 25.0° with respect to the axis of the first polarizer (nearest the light source). What is the fraction of incident unpolarized light intensity transmitted by the combination of polarizers? (Assume each polarizer is ideal.) I / Imax =
