Interference and Diffraction

  1. Sep 24, 2014 #1
    1. The problem statement, all variables and given/known data
    Write down the intensity equation for a two-slit interference pattern with diffraction effects included. Indicate which part originates from double-slit interference and which part from single-slit diffraction. What happens when the angle = 0


    2. Relevant equations
    IDouble=4*I*cos2[(pi*d)/(lambda*L)]y

    ISingle=Io[sin2(pi*a*sin(theta)/lambda)]/(pi*a*sin(theta)/lambda)2


    3. The attempt at a solution
    My book doesn't mention anything about ISingle so I'm not sure if that is the correct equation. I am not sure where to begin.
