"cosine law": either of two laws of radiation: a: the radiant flux emitted in a given direction from a given small area of a perfectly diffusing surface varies as the cosine of the angle of emission. b: the irradiation by parallel rays falling on a surface varies as the cosine of the angle of incidence. 1, record 1, English, - cosine%20law

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

"Bouguer law": The law discovered by Bouguer in 1729, that the absorption of light in homogeneous materials depends on thickness according to the exponential expression given under absorption coefficient. 1, record 2, English, - Bouguer%20law
Record number: 2, Textual support number: 1 OBS
The law was rediscovered by Lambert and is often referred to as the Lambert law of absorption. It is also related to the Beer law, which is obtained by setting the absorption coefficient a = a[alpha]c. When the law is expressed in terms of common logarithms: I = I010- kx, "k" is known as the extinction coefficient. These laws may be applied to a narrow band of wavelengths, giving the specular coefficient of absorption or the specular extinction coefficient according to the form of the equation used. 1, record 2, English, - Bouguer%20law
