Light scattering and light absorption coefficient The light scattering coefficient, s, in m2/kg and the light absorption coefficient, k, in m2/kg play central roles in paper optics and these are calculated according to Kubelka-Munk theory. The light scattering (s) and light absorption (k) coefficients are important because they are of fundamental importance in many basic
