3. Particle description

The simplest form is spherical. The particle's size is then described by a single length (its radius r or diameter d). In light scattering, the size parameter is used instead: $α = \frac{π d}{λ}$

where the diameter is scaled by the wavelength.

Rayleigh and geometrical optics theories are obtained for the limits $α \to 0$ and $α \to \infty$ respectively.

If the particle material is homogeneous, isotropic...
