(CC BY-NC; Ümit Kaya via LibreTexts) By the 1890’s, experimental techniques had improved sufficiently that it was possible to make fairly precise measurements of the energy distribution of blackbody radiation. Web8.2 Blackbody radiation. Blackbody radiation is the upper limit on the thermal emission intensity from a solid surface (Wolfe, 1989; Zalewski, 1995 ). It is based upon Planck’s Law for oscillators, which in turn is derived by using the Bose-Einstein distribution for vibrations in a box (a ‘holeraum’) of macroscopic dimension. csn fort saskatchewan
