Light Slit Experiment

  1. May 19, 2009 #1
    If one slit is used instead of 2 in a diffraction experiment, how does light intensity vary?

    I think.. Central fringe brighter, symmetrical fringes either side of central fringe, central maximum twice the width of side fringes..

    But I'm not sure why?

    Also, using diffraction gratings – why is the maximum brightness in the middle?

    Think about why fringes exist at all when you have 2 slits. Does the same reasoning apply with 1 slit?
