2. Using the laws of light scattering in accordance with the Rayleigh theory and the attenuation of the light flux in accordance with the Bouguer-Lambert-Beer law, calculate the radius of the divinylstyrene latex particles based on the results of measuring the optical density D in a 5.01 cm long cuvette at a wavelength of λ:
Latex concentration, g/l 0.7
λ, nm 540
D 0.303
The density and refractive index of the dispersed phase are 0.945 g/cm3 and 1.653; the refractive index of water is 1.333.
