WebA body that emits the maximum amount of heat for its absolute temperature is called a blackbody. A blackbody is an idealized physical body that has specific properties. By definition, a black body in thermal equilibrium emissivity of ε = 1.0. Real objects do not radiate as much heat as a perfect black body, and they radiate less than a black ... WebFor example, temperature of the sun is very high (6000 K approx.) it emits all possible radiation so it is an example of black body.

It is a doubled walled evacuated spherical cavity whose inner ...
WebMar 3, 2024 · blackbody, also spelled black body, in physics, a surface that absorbs all radiant energy falling on it. The term arises because incident visible light will be absorbed rather than reflected, and therefore the surface will appear black. The concept of such a … A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. The name "black body" is given because it absorbs all colors of light. A black body also emits black-body radiation. In contrast, a white body is one with a "rough surface that reflects all incident rays completely and uniformly in all directions."
