Homework Help: Waves and Optics

  1. Jan 18, 2016 #1
    1. The problem statement, all variables and given/known data
    An unpolarised light beam is shone horizontally through a cubic tank filled
    with weakly scattering fluid. Can vertically polarized light leave through the sides that are parallel to the beam’s propagation direction?

    2. Relevant equations

    3. The attempt at a solution
    My thinking is that they can. If the fluid is weakly scattering the chances are that a small amount of light would be able to leave through the top sides and that this would have vertically polarised light. Any ideas on how to approach this problem?

    If the light is scattered straight up through the top then I don't see how it could be vertically polarised. But if you change it to scattering horizontally through the sides I would agree. Mind you, I'm no expert on this topic.

    Wouldn't that mean it is possible?
