This article describes the vortex model of the microcosm, the structure of fundamental particles and the mechanism of interaction of microobjects. Disclosed is a mechanism for interaction of photons with substance atoms. Models of atoms and molecules as vortex formations were built. Analysis of the properties of the vortex field made it possible to find out the essence of gravity. Maxwell's equations were modified and the vortex nature of radio waves was shown. Within the framework of these ideas, the physical meaning of the basic concepts of mass, charge, gravity and radio waves is clarified.
