A black body (also blackbody) 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 [that] reflects all incident rays completely and uniformly in all directions..y definition, a black body in thermal equilibrium has an emissivity of Îµ = 1.0. A source with lower emissivity independent of frequency often is referred to as a gray body. Construction of black bodies with emissivity as close to one as possible remains a topic of current interest.
