It is proved that the system of Maxwell-Lorentz equations is derived from the system of equations of the compressible oscillating ether proposed by the author. It is shown that the classical electromagnetic wave describes only the transverse component of the propagation of a screw longitudinal-transverse wave in the ether while maintaining a constant ether density. And that the Maxwell-Lorentz equations are unsuitable for describing the propagation of longitudinal waves in the ether of variable density (waves of radiant electricity by Nikola Tesla).
