Homework Help: Double-slit: what causes the altering problem

  1. Nov 6, 2009 #1
    1. The problem statement, all variables and given/known data

    It should be obvious that the simple interference of two waves is not the only that you have seen with the double slit. What other phenomenon is altering your pattern?

    2. Relevant equations

    3. The attempt at a solution

    I'm assuming that the intensity of the light of the laser, but that would not alter the pattern, it would just be less of it. Also the slit separation would contract/expand the pattern, but it would essentially be the same.

    What if there were only one slit?
