Homework Help: Polarization, minimum thickness of a quarter wave plate

  1. Sep 25, 2011 #1
    1. The problem statement, all variables and given/known data

    show that minimum thickness of quarter wave plate is d=[itex]\lambda[/itex]0/4(n1-n2

    2. Relevant equations


    3. The attempt at a solution

    for quater wave plates wavelengths must differ by 1/4
    i can see its simple but i just cant see what i do

    We do have software to calculate the thickness for wave plate, different wavelength design.
