WebThe solid black line is the real spectrum; you can see that it's much more complicated than a simple, smooth continuum. Nonetheless, you can at least get a general idea for the temperature of the hot gas around this star by fitting a rough blackbody curve to it -- as is shown by the upper thin blue line. WebQuantizing Electrons in the Radiator. In 1900, the German physicist Max Planck (1858–1947) explained the ultraviolet catastrophe by proposing that the energy of electromagnetic waves is quantized rather than continuous. This means that for each temperature, there is a maximum intensity of radiation that is emitted in a blackbody … 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." how to score a duck

So, quantization does not mean only atom, it can be examined for many situations in the real life. Another thing I should mention that blackbody radiation curves are specific to material temperature. 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.
