Per simplicitat, aquí es parla de «reflexions», però en forma més general, les interfases entre les petites partícules que constitueixen molts dels materials són irregulars en una escala comparable a la longitud d'ona de la llum.

For simplicity, "reflections" are spoken of here, but more generally the interface between the small particles that constitute many materials is irregular on a scale comparable with light wavelength, so diffuse light is generated at each interface, rather than a single reflected ray, but the story can be told the same way.
