A previously obtained empirical relationship describing light scattering as a function of particle concentration and size was examined in view of classical light scattering theory. Although the particle size range used to develop the equation covered both a region where theory predicts that haze intensity should be a function of r4/lambda-squared (where wavelength, lambda, is approximately equal to particle radius, r) and one where haze intensity should be a function of r2 (where r > lambda), the empirically derived equation predicted that haze intensity was proportional to particle radius squared. This may have resulted from a dependence on either particle surface area or cross-sectional area.
