Homework Statement
Estimate maximum slit width of a double slit.
Homework Equations
The Attempt at a Solution
Letting the slit width be a,
The intensity profile of such a system is:
[tex]I = I_0 sinc^2\left( \frac{Nkasin \theta}{2} \right) cos^2\left( \frac{kd sin\theta}{2} \right)[/tex]
I suppose the maximum slit width is when a = d? Such that all the interference maxima coincides with the minima from diffraction envelope. But physically this would mean that both slits collapse into one..
