<P> In 1901 , Max Planck published an analysis that succeeded in reproducing the observed spectrum of light emitted by a glowing object . To accomplish this , Planck had to make an ad hoc mathematical assumption of quantized energy of the oscillators ( atoms of the black body ) that emit radiation . Einstein later proposed that electromagnetic radiation itself is quantized , not the energy of radiating atoms . </P>
