This term was first used by Gustav Kirchhoff in relation to his work in spectroscopy.  Wilhelm Wien considered the effect of temperature on them in his Displacement Law, and another important relation involving their temperature is established in the Stefan-Boltzmann Law.  Wien's Distribution Law and the Rayleigh-Jeans Law both failed to predict their emission spectra for all wavelengths, but these shortcomings were solved by Planck's Law dealing with their radiation. FTP, name these objects which absorb all electromagnetic radiation and are ideal thermal radiators.          |
