Blackbody Radiation
This chapter provides the fundamental notions about black body and its radiation.
But, now at the beginning a little bit of
history on this subject. For a quite long time, more than 35 years, black body
radiation was “a thing-in-itself”. Only in 1895 Wien and Lummer tried to
develop a module with which to verify and test experimentally the module of an
ideal black body presented by Kirchhoff.
