Homework Help: Thin film diffraction - need help to start

  1. May 13, 2012 #1
    Thin film diffraction -- need help to start

    1. The problem statement, all variables and given/known data

    I attached a picture of the problem, could anyone tell how I would begin to proceed with this problem? I believe that it is more complicated than simply a Snell's law problem, due to the thin film of oil.

    Thanks for your consideration.

    2. Relevant equations



    3. The attempt at a solution

    All you need is snell's law. However, you will need to use it twice.
