9. 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 divinylstyrene latex particles from the results of measuring the optical density D in a cuvette 5.01 cm long at light wavelength λ: latex concentration 0.5 g/l, λ= 440 nm D=0.402. The density and refractive index of the dispersed phase is 0.952 g/cm3, and 1653, the refractive index of water is 1.333.
