When the light irradiates the atom, the changing electromagnetic field produced by the light will make the electron and the nucleus move in the opposite direction and make the atom become an electric dipole. The frequency of the changing dipole moment is basically the same as that of the changing electromagnetic field produced by the incident light. At the same time, the properties of the secondary electromagnetic field generated by the electric dipole in the opposite direction of the incident light are exactly opposite to those generated by the incident light; the properties of the secondary electromagnetic field in the same direction of the incident light are exactly the same as those generated by the incident light; the directions of the secondary electromagnetic field in other directions are at a certain angle with the direction of the incident light. Therefore, the phase difference between the secondary electromagnetic field and the incident light generated by the atoms at the interface of the medium will be different due to the angle between the secondary refraction / transmission light and the incident light, and there is no phase difference between the secondary refraction / transmission light and the incident light, while the phase difference between the reflected light and the incident light is half cycle.<br>
