Rayleigh gans approximation
WebJan 31, 2024 · In this work, the Rayleigh–Gans–Debye (RGD) approximation has been used to explain theoretically the form of the whole turbidity curve in a homocoagulation process. To estimate the turbidity of a suspension of particles, it is necessary to calculate the light scattering cross section of the particles and aggregates. Rayleigh scattering describes the elastic scattering of light by spheres that are much smaller than the wavelength of light. The intensity I of the scattered radiation is given by where I0 is the light intensity before the interaction with the particle, R is the distance between the particle and the observer, θ is the scattering angle, λ is th…

Since these aerosols are agglomerates composed of … WebThe two-volume elements will scatter the light with the same phase but different amplitudes, thus interference will not be completely destructive. One simple yet very useful theory describing the light scattering of colloidal samples is the so-called Rayleigh-Gans-Debye (RGD) theory. Its basic assumption is that light is not reflected at the ...
