(from the article `light`) Blackbody radiation refers to the spectrum of light emitted by any heated object; common examples include the heating element of a toaster and the ... ...Such an ideal object absorbs and thus emits radiation of all frequencies equally and fully. A radiator/absorber of this kind is called a ... ...was follow...

Any physical body absorbs and emits electromagnetic radiation when its temperature is above absolute zero. Planck's law determines the radiant flux of a body at a specific wavelength. In atmospheric chemistry, the calculation involving the earth's blackbody radiation shows that the earth's surface temperature would be below the freezing point of wa...

The radiation -- the radiance at particular frequencies all across the spectrum -- produced by a blackbody -- that is, a perfect radiator (and absorber) of heat. Physicists had difficulty explaining it until Planck introduced his quantum of action.

The electromagnetic radiation emitted by an ideal black body; it is the theoretical maximum amount of radiant energy of all wavelengths which can be emitted by a body at a given temperature.The spectral distribution of black-body radiation is described by Planck law and the related radiation laws. If a very tiny opening is made into an otherwise co...
