In this article two types of diffraction are considered: the macroscopic diffraction occurs whether with electromagnetic waves or with photon beams like light, the photon diffraction or nanoscopic diffration occurs only with photons. The difference between the two diffractions depends on both the width of the slot and the wavelength of radiation. This consideration proves further that electromagnetism and optics, including in optics infrared, visible, ultraviolet and X radiation, have a different physical nature: electromagnetism is characterized by waves, optics by photon beams. The frequency band employed by infrared radiation represents the point of connection between the two diffractions and the two physical behaviours.
