![]() ![]() Interaction of initially motionless mass body and a graviton. Let’s solve the previous task only instead of interaction of a photon and initially motionless mass body we shall consider interaction of a graviton and a mass body ( Figure 1).įigure 1. In it the main difference of a graviton from a photon. Therefore, as against a photon, the graviton cannot be in photon space. Physically the graviton represents local wave perturbation of the Riemann’s space-time. There is cyclic frequency of a graviton-frequency of the Riemann’s space-time fluctuations. The electric charge of a graviton is equal to zero. Polarization of a graviton will be in detail considered below. A graviton has two directions of polarization. ![]() There are basic properties of a graviton.Ī graviton is a quantum particle a carrier of gravitational interaction.Ī graviton is boson, it is stable. In connection with that quantum electrodynamics is in detail developed science all further attention we shall give a graviton. Feynman has offered the good approximated method of the solution of similar problems. Therefore accurately to solve above the offered task it is impossible. Since the reference system in photon space moves with a light velocity the calculation demands also the mass particle moved with light velocity that is impossible. It reflects fact that the photon is not in Euclidian space, as against a mass particle. This at first sight the absurd result is not casual. Thus after absorption of a photon the particle starts to move with speed of light. Having divided the law of energy conservation on the law of an impulse preservation we shall receive The law of energy conservation in the relativistic form can be written down as: Where c there is a light velocity in vacuum, V-a velocity of a particle after absorption of a photon, m-its relativistic mass, The law of preservation of an impulse at absorption of a photon by a motionless particle looks like: Let’s consider as an example interaction of a photon and a mass particle in an elementary case when the mass particle initially is rested. ![]() We shall not stop on essence of these approximations, and we shall consider a simple model task. However the Feynman’s theory is approximated. Feynman’s works which has offered so-called “a diagram method” of this interaction calculation. The theory of a photon and an electron interaction it is a basis of the part of physics-quantum electrodynamics. On the other hand for photons the wave phenomena are inherent: diffraction and interference. Using corpuscular properties of a photon Einstein has explained the phenomenon of a photo effect. It is absorbed and radiated by particles of substance (for example, atoms) entirely. On the one hand the photon behaves as a particle. For example, in a laser beam theoretically all photons are identical and coherent.įor photons it is characteristic corpuscular-wave dualism. In the same energy state there can be an infinite set of photons. As against fermions (for example, electrons) for photons the Pauli’s exclusion principle does not operate. The magnetic moment of a photon is equal to zero. From the point of view of classical electrodynamics it is two possible circular polarizations: right-polarized and left-polarized. The sign ± reflects two possible helicity of a photon. Spin of the photon is directed along a direction of a photon movement and is equal There is the module of a wave vector of a photon (or wave number), The photon in vacuum moves with light velocity The mass of a photon is always equal to zero. in vacuum spontaneously does not disintegrate. The photon-absolutely stable particle, i.e. Photon (Greek “light”) or quantum of electromagnetic radiation-an elementary particle with which help electromagnetic interaction between charges is carried out. We list the basic properties of a photon. Therefore, polarization of a photon has a vector character, and polarization of a graviton has a tensor character. But in the given work, we shall not pay attention to this distinction.įirst of all, we shall notice that a photon-a vector particle in the sense that the electromagnetic field is described by the vector Maxwell’s equations, and the graviton-a tensor particle because the gravitational field is described by the tensor Einstein’s equation. ![]() Perhaps, the main distinction between these particles consist that the first is real, and the second is hypothetical. The photon and the graviton are two quantum particles responsible for interaction with physical objects of two long-range action fields: electromagnetic and gravitational. During research of quantum properties of particles frequently, there is a desire to compare, at first sight, very similar particles: a photon and graviton. ![]()
