This emission is called blackbody radiation. A room temperature blackbody appears black, as most of the energy it radiates is infra-red and cannot be perceived by the human eye.

WebA blackbody is an object that absorbs all of the radiation that it receives (that is, it does not reflect any light, nor does it allow any light to pass through it and out the other side). The energy that the blackbody absorbs heats it up, and then it will emit its own radiation. WebAug 15, 2024 · No, a black body is described as “black” because it absorbs all light incident on it. A black body emits a continuous spectrum of electromagnetic radiation which peaks at a certain wavelength.
