Planck, who was a colleague of Wien's when he was carrying out this work, later, in 1900, based quantum theory on the fact that Wien's law, while valid at high frequencies, broke down completely at low frequencies.
Planck, na isang kasamahan ng Wien's kapag siya ay dala ang mga ito sa trabaho, mamaya, sa 1900, base sa quantum theory ang katunayan na ang Wien ng batas, habang may-bisa sa mataas na frequencies, Nasira kumpleto at low frequencies.
