7. Using the data on the optical density of polystyrene latex (polystyrene hydrosol) at various wavelengths, calculate the average radius of the latex particles:
Dλ 0.125 0.127 0.099 0.049
λ , nm 425 485 527 685
Geller calibration curve n=f(d) build according to the following data:
d, nm 77.0 88.0 95.0 106.7 110.0 119.0 132.0 133.0 158.0 443.0
n 3.82 3.64 3.54 3.30 3.23 3.04 2.82 2.66 2.45
Where n is the dispersion index; d is the particle diameter.
