A beam of polarized light is sent into a system of two polarizing sheets. Relative to the polarization direction of that incident light, the polarizing directions of the sheets are at angles u for the first sheet and 90° for the second sheet. If 0.10 of the incident intensity is transmitted by the two sheets, what is u?
