It also absorbs all electromagnetic radiation incident on it irrespective of wavelength. A hollow enclosure maintained at a uniform temperature, with a small opening compared to its size and a conical ...
WebA black body (or blackbody) is a term used in physics to refer to an object that absorbs all incoming energy, no matter its frequency. Black bodies have no reflective power, so no radiation is reflected, and the object appears black to the eye. Black bodies can also emit radiation (called black body radiation), which is done perfectly (without ...
