*Crystalline structure: whether the atoms or molecules exhibit the 'long-range order' evidenced in crystalline solids.

*Glassy structure: scattering centers include fluctuations in density or composition.

*[[Microstructure]]: scatteringScattering centers include internal surfaces such as grain boundaries, [[crystallographic defect]]s, and microscopic pores.

*Organic materials: scattering centers include fiber and cell structures and boundaries.

[[Diffuse reflection]] - Generally, when light strikes the surface of a (non-metallic and non-glassy) solid material, it bounces off in all directions due to multiple reflections by the microscopic irregularities ''inside'' the material (e.g., the [[grain boundaries]] of a [[polycrystalline]] material, or the [[Cell (biology)|cell]] or [[fiber]] boundaries of an organic material), and by its surface, if it is rough. Diffuse reflection is typically characterized by omni-directional reflection angles. Most of the objects visible to the naked eye are identified via diffuse reflection. Another term commonly used for this type of reflection is "light scattering". Light scattering from the surfaces of objects is our primary mechanism of physical observation.<ref name="z">{{cite book|author=Kerker, M.|title=The Scattering of Light|publisher=Academic, New York|year=1969|author-link=Milton Kerker}}</ref><ref name="y">{{cite journal
