A Sub Microscopic Description of the Diffraction Phenomenon
  It is shown that a detailed sub microscopic consideration denies the wave-particle duality for both material particles and field particles, such as photons. In the case of particles, their \psi-wave function is interpreted as the particle's field of inertia and hence this field is characterised by its own field carriers, inertons. Inertons and photons are considered as quasi-particles, excitations of the real space constructed in the form of a tessel-lattice. The diffraction of photons is explained as the deflection of photons from their path owing to transverse flows of inertons, which appear in the substance under consideration at the decay of non-equilibrium phonons produced by transient photons.
