In single slit fraunhofer diffraction, only the light which goes near the slit is diffracted... If it goes just through the middle it will not be... If the slit is really small would light be diffracted even if it goes through middle?And do all light waves that go near the slit diffract? Does all light that goes through the middle go undiffracted and contribute to central maximum? What would be the classical and quantum interpretation of this question?
