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 or fiber boundaries of an organic material ), and by its surface, if it is rough.
