When the slits are very close together, it is as if there were just one slit, and we see a basic diffraction pattern, however once we spread out the slits, we can start to see interference when waves passing through the two different slits interfere with each other. Write about the difference in the diffraction patterns between spacings less than and greater than the wavelength size.
