Definition of "blackbody" |
A theoretical object that radiates the maximum amount of energy at a given temperature, and absorbs all the energy incident upon it. A blackbody is not necessarily black. (The name blackbody was chosen because the color black is defined as the total absorption of light energy.) . / theoretically contrived object that gives rise to the so-called “black body radiation.” One might imagine a closed surface object (say of metal) possessing one opening that connects the interior surface with the outside world. When the object is heated, the opening becomes a perfect “black” radiator. Such radiation depends on temperature only. |
