These three laws, named for the 18th century physicist who stated them, hold that the illuminance of a surface is inversely proportional to the square of its distance from the light source, that if the light hits the surface at an angle theta, the illuminance is proportional to cosine theta, and that the luminous intensity of light decreases exponentially with the distance that it enters a medium.
