Homework Help: Radiation pressure

  1. Nov 17, 2012 #1
    1. The problem statement, all variables and given/known data

    I have an exam on Monday and I'm trying to get a few concepts straight before then. I have a few questions...

    1) p = E/c for a photon. Is this also true for a wave?
    2) Assuming complete absorption, radiation pressure is 1/c x Poynting vector. What happens when there's reflection?
    3) Anyone know a good reference for understanding how polarizes work? My notes aren't very good.


    2. Relevant equations

    3. The attempt at a solution

    I am not 100% sure but I believe reflection is an absorption and re emission however I would consult with your professor because some tests and texts assume a photon bounces rather than becomes re emitted or phase shifted. Also Hyperphysics has some great overviews on the concepts ! I hope this helps!
