diffuse reflection

Diffuse reflection is the reflection of light from an uneven or granular surface such that an incident ray is seemingly reflected at a number of angles. It is the complement to specular reflection. If a surface is completely nonspecular, the reflected light will be evenly spread over the hemisphere surrounding the surface (2×π steradians).

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