Dark fringes for single-slit diffraction

  1. Oct 27, 2010 #1
    How many dark fringes will be produced n either side of the central maximum if light (its wavelength is 651 nm ) is incident on a single slit that is 5.47x10^-6 m wide?


    sin (theta) = m.wavelength/w

    Looks good. Find theta when m = 1. Then for m = 2, and so on until it doesn't work anymore.
