Double slit experiment

  1. Sep 16, 2013 #1
    1. The problem statement, all variables and given/known data

    I need to derive the intensity distribution of the double slit experiment. Intensity as a function of the slit separation d, the distance to the screen L and the wavelength [itex]\lambda[/itex]. L>>d

    2. Relevant equations



    3. The attempt at a solution

    Ok this is ridiculous but everything I find is just telling me how to find the minimum or maximum. I also need to figure this out for the triple and N slit problems.

    I know that intensity is basically the square of the electric field. So I have been trying to make two waves and then add them together and then square them. I keep going wrong here. Is there an online resource that takes this approach?

    Please show your work then, so we can see what you did and what went wrong. The basic idea is right.
