The change in the direction of radiation into all directions after encountering a rough surface. Compare specular reflection. Term frequently applied to the process by which solar radiation is scatter [..]

See Reflection, diffuse

Reflection from a rough or irregular surface which does not maintain the integrity of the incident wavefront.

Light rays reflected in many random directions, as opposed to the parallel rays reflected from a perfectly smooth surface such as a mirror

Type of reflection that occurs when parallel light waves strike an uneven surface and bounce off in many different directions (Lesson 22)

  Reflection of incident light in all directions from a surface, so that diffuse illumination of a surface is visible to all viewers, independent of the viewer's position.

Diffusion by reflection in which, on the macroscopic scale, there is no regular reflection.
