Homework Help: Double Slit Problem

  1. Nov 27, 2005 #1
    here the problem:

    In the Young Double Slit experiment, alternatingbands of bright and dark regions are produced on the screen. At the dark band shown in the picture below, on slit is a closer than the other slit: In other words, D1 is less than D2, Find D2-D1, Assuming that the light has a wavelength of 500nm.

    The Picture he shows, he said is not to scale so it wont help. there are no other measurements listed. How do i go about figuering this out????

    I hope there's an angle scale in the pic.

    Distance between slit centers "d" makes fringes (bands) that are angle-dependent, as [tex]m \lambda = d sin \theta[/tex]
