Based on empirical studies, we show that the "diffractive-interferential" images produced in laser light experiments are generated by a completely unknown, non-wave phenomenon. We show that the phenomenon is generated by barriers that create the slits. Presumably, the mechanism of this phenomenon is related to the scattering caused by collisions of photon beams with strange spatial structures of physical fields of a strange nature and which are generated by charged particles of the barrier's atomic lattice. We indicate the probable mechanism of the physical phenomenon corresponding to these scatterings. We hypothesize that the same phenomenon also gives rise to the characteristic quantum discreteness of the microscale, and that further, more detailed empirical and theoretical investigation of this phenomenon will lead to the necessity of implementing significant changes in fundamental concepts of physics.
