WebPlanck discovered the curve now known as Planck's law in October of that year and presented it in December. Planck's original intent was to find a satisfactory derivation of Wien's expression for the blackbody radiation curve, which accurately described the data at high frequencies. Planck found Wien's original derivation inadequate and devised ... WebMay 1, 2015 · Contrary to a popular belief, Planck was not concerned by the "ultraviolet catastrophe" (Ehrenfest's nickname from 1911) in black body radiation, when the energy gets converted into higher and higher frequency waves in ether, which is a commonly given back engineered motivation.
