Universality of Mie Scattering

The universality of Mie scattering means that the way particles scatter light depends mainly on their size relative to the wavelength, not on their specific material or shape. When light hits particles of a similar ratio of size to wavelength, they behave in a predictable, consistent manner, regardless of what the particles are made of or their exact form. This principle allows scientists to understand and model how different particles scatter light across various substances, making the behavior largely universal for particles sharing similar size-to-wavelength ratios.
