1. The problem statement, all variables and given/known data A 200 mW horizontally polarized laser beam passes through a polarizing filter whose axis is 25 degrees from vertical. What is the power of the laser beam as it emerges from the filter? P=mW 2. Relevant equations E (transmitted) = E (incident)cos() 3. The attempt at a solution 200= E(incident) cos (25) E(incident) = 2.206*10^2 Not sure if this is correct..this is my last attempt at the question, need to know if I'm approaching this correctly at all?!?! Thanks!
