graybody
A hypothetical “body” that absorbs some constant fraction, between 0 and 1, of all electromagnetic radiation incident upon it. This fraction is the absorptivity and is independent of wavelength. As such, a graybody represents a surface of absorptive characteristics intermediate between those of a white body and a blackbody. No such substances are known in nature.
