Double Slits experiment

  1. Mar 8, 2012 #1
    1. The problem statement, all variables and given/known data
    In a double slits experiment, the intensity at the central fringe is I. What will be the intensity at the central fringe when each slit is widened 2 times?


    2. Relevant equations



    3. The attempt at a solution

    My suggestion is that the intensity will be 2I...

    But what is the reasoning?
    What is the relationship between the central fringe intensity and the slit width?

    I think that when the width of the each slit is doubled then the amount of light passing through will be double as well as the intensity
