A Fraunhofer diffraction pattern is produce on a screen

  1. Feb 23, 2012 #1
    1. The problem statement, all variables and given/known data
    A Fraunhofer diffraction pattern is produced on a screen 218 cm from a single slit. The distance from the center of the central maximum to the first-order maximum is 7620 times the wavelength (lambda). Calculate the slit width. Answer in __m


    2. Relevant equations



    3. The attempt at a solution

    I have no idea how to even start this problem but this is what I tried.

    7620 = (1.5 * 2.18)/a where a is the slit width.
    This was not correct. I would really appreciate any kind of help on this!
