A black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.
A white body is one with a "rough surface reflects all incident rays completely and uniformly in all directions."
An approximate realization of a black surface is a hole in the wall of a large enclosure.
