A square aperture with a side of length 0.5 mm is illuminated at normal incidence with a parallel beam of coherent light of wavelength 550 nm. According to Fraunhofer diffraction theory, at what distance from the aperture would the diffraction pattern have a central maximum with a width also equal to 0.5 mm? What can you say about the Fraunhofer condition under these circumstances?
