Find the Fraunhofer diffraction pattern for two infinite (in the y-direction) slits separated by a distance D from each other and with width d along the x-axis. By making them infinite in one dimension, we have reduced the algebra to 1 integral over x. By slit, I mean that they transmit 100% for light inside d and 0% for light outside of d. Plot the result for a=400nm and 600nm.
