R

This is a linear elastic scattering process caused by the presence of sub-microscopic variations in the density and composition of the glass, leading to localised index variations. A fraction of the propagating light will scatter off these variations in all directions, some of which will end up propagating in the backwards direction. This scattering decreases according to a fourth-power law as wavelength increases (i.e. 1/λ⁴).
