10.11. According to the dependence of light scattering (IP) on the number (v) and magnitude (V) of colloidal rosin particles, show the applicability of the Rayleigh equation for these systems.
Particle volume V, μm3 0.0134 0.0135
The number of particles v in 1 cm3 3496 * 10 ^ 6 1732 * 10 ^ 6
Light scattering IP, a 22.4 * 10 ^ –10 13.28 * 10 ^ –10
