单词	Lambert's laws
释义	Lambert's laws (1) The illuminance of a surface illuminated by light falling on it perpendicularly from a point source is inversely proportional to the square of the distance between the surface and the source. (2) If the rays make an angle θ with the normal to the surface, the illuminance is proportional to cosθ. (3) (Also called Bouquer's law ) The luminous intensity (I) of light (or other electromagnetic radiation) decreases exponentially with the distance d that it enters an absorbing medium, i.e. I = I_oexp(-αd) where I_o is the intensity of the radiation that enters the medium and α is its linear absorption coefficient . These laws were first stated (for light) by Johann H. Lambert
