1. The problem statement, all variables and given/known data QUESTION: Consider linearly polarized light of the form: E=|E|cos(kx-wt)(ì+j) where i and j are the standard unit vectors. What is direction of polarization of this lightwave? 2. Relevant equations 3. The attempt at a solution this is the first time i tackle a problem like this and i'm not sure where to start..i can see the wave is traveling in the positive x-direction, and i'm guessing the i and j indicate polarization...but im not sure how any explanations would be grrrreatly appreciated..thankyou!!!
