We show thatthe photon trajectory calculated on the basis ofthe Newton laws of mechanics coincides with that calculated on the basis of laws of the geometrical optics on assumption that the momentum of the photon in matter increases by n times as compared with that in free space. The force applied to the photon is calculated from the third Newton law as the force that is opposite to the net force produced by the electrical field of the photon in the matter. It is shown that there is no Lorentz force and the Maxwell force produced by an electrical filed in a dielectric is responsible for a change of the photon momentum.
