The one-loop radiative corrections to the photon propagator, called vacuum polarization, can be represented by the Feynman diagram of the second order. The physical meaning of this diagram is the virtual proces, where photon can exist in the intermediate state with an electron and a positron being the virtual particles. The photon propagation function based on such process is determined in the framework of he Schwinger source QED methods. Then, the modication of the Brag equation is derived.
