Homework Statement
Unpolarized light passes through two polarizers whose transmission axes are at an angle of 28.1° with respect to each other. What fraction of the incident intensity is transmitted through the polarizers?
Homework Equations
I=.5xIoxcos^2(theta)
The Attempt at a Solution
Im pretty sure that i have the correct equation, but I'm confused because in the problem I am not given an Incident Intensity, therefore how can i solve for the transmitted intensity? If someone could please start me in the right direction, i would appreciate it very much!
