Consider the three optical scattering properties, µ_{s}, g, and µ_{s}(1 - g), as functions of wavelength for a spherical particle with n_{p} = 1.5721 in a medium with n_{med} = 1.3316 at a concentration of 0.1% volume fraction (f_{v} = 0.001). Assume that n_{p} and n_{med} are constant versus wavelength for this example calculation.
Let the sphere be one of three sizes: 0.100 µm, 0.300 µm, and 1.00 µm.
The Mie theory calculation yields:
Note: The true n_{p} and n_{med} for polysytrene spheres and water are slightly wavelength dependent and would deviate slightly from the above example.
