The reflection of point sources of light by matte, or diffuse, surfaces (those that scatter light equally in all directions) is modeled by Lambert's cosine law which states that intensity varies as the cosine of the angle between the direction of the light source and a vector perpendicular to the surface, called the surface normal. 5, record 1, English, - cosine%20law

"cosine emission law" [states that] the energy emitted by a radiating surface in any direction is proportional to the cosine of the angle which that direction makes with the normal. 4, record 1, English, - cosine%20law
