Black bodies physics
WebBlack Body Radiation. Black body radiation is the name given to the thermal radiation emitted by all bodies (objects) All objects, no matter what temperature, emit black body radiation in the form of electromagnetic waves. These electromagnetic waves usually lie in the infrared region of the spectrum but could be emitted in the form of visible ... WebKirchhoff's original contribution to the physics of thermal radiation was his postulate of a perfect black body radiating and absorbing thermal radiation in an enclosure opaque to thermal radiation and with walls that absorb at …
