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 ... WebSep 12, 2024 · The blackbody radiation curve was known experimentally, but its shape eluded physical explanation until the year 1900. The physical model of a blackbody at …

When a black body is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. Its emission is called black-body radiation. The concept of the black body is an idealization, as perfect black bodies do not exist in nature.
