Recently we used the quantum structure of electromagnetic waves (QSEW) to describe patterns of the single slit experiment and its diffraction. In the QSEW, we have claimed that a photon is not the quantum of electromagnetic waves and has a three-dimensional structure made of one-dimensional energies. The photon can gain or lose one-dimensional quanta energies (diffraction patterns) and even share them (Redshift). At the time of losing or gaining one dimensional quanta energies of each photon the direction of the axis of oscillation of the photon can change. the QSEW explains the effect of the observer and predict displacement of the pattern of the double slit experiment after changing distance of the detector. The paper proposes using the trajectory tree pattern of the QSEW to describe interference patterns of particles in the double-slit experiment.
