"At the atomic scale, an electromagnetic wave's phase velocity is slowed in a material because the electric field creates a disturbance in the charges of each atom (primarily the electrons) proportional to the electric susceptibility of the medium. (Similarly, the magnetic field creates a disturbance proportional to the magnetic susceptibility.) As the electromagnetic fields oscillate in the wave, the charges in the material will be "shaken" back and forth at the same frequency. The … " - Refractive index explanation

WebThe meaning of refraction. In principle, light travels in a straight line as long as there is no event to stop it from doing so. A change of materials, also called media, through which the light is travelling is such an event. Because light is a wave, it may be absorbed, transmitted, reflected, or a combination thereof.
