Boldyreva boldyrev-m@yandex.ru 1 The State University of Management Characteristics of three types of photon used in the descriptions of optical experiments demonstrating the properties of light are discussed: C-photon – a quasi-monochromatic electromagnetic radiation localized in space, M-photon – a hypothetical elementary particle of the light field, and Q-photon – an objective entity corresponding to the Fock state of the light field. Some properties of superfluid 3Не-В are analyzed and equations are derived describing a vortex-wave process in the medium similar to superfluid 3Не-В. The comparison of the properties of light and those of vortex-wave process in the medium similar to superfluid 3Не-В shows that there is an analogy between the properties of light and the properties of the process. The analogy found allows one to offer a physical model describing such properties of light as the constancy of its speed in inertial frames of reference, and quantum correlations of photons. http://pubs.sciepub.com/ijp/3/2/5/ijp-3-2-5.pdf photon speed of light quantum correlations spin supercurrent superfluid physical vacuum vortex-wave process
