blackbody Explained

blackbody at English => English (The Britannica Concise) Of Explained:

Theoretical surface that absorbs all radiant energy that falls on it, and radiates electromagnetic energy at all frequencies, from radio waves to gamma rays, with an intensity distribution dependent on its temperature. Because all visible light falling on such a surface is absorbed without reflection, the surface will appear black as long as its temperature is such that its emission peak is not in the visible portion of the spectrum. See also absorption.

blackbody at English => English (WordNet) Of Explained:

n : a hypothetical object capable of absorbing all the
electromagnetic radiation falling on it; "a black body
maintained at a constant temperature is a full radiator
at that temperature because the radiation reaching and
leaving it must be in equilibrium" [syn: {black body}, {full
