Thin Films again - Help?

  1. Apr 29, 2009 #1
    1. The problem statement, all variables and given/known data

    A camera lens (n = 1.90) is coated with a thin film of magnesium fluoride (n = 1.40) of thickness 90.0 nm. What wavelength in the visible spectrum is most strongly transmitted through the film?

    2. Relevant equations


    3. The attempt at a solution

    I have no idea where to start, is there an equation that will use both n's at once?
