... was struggling, trying to find an explanation for the behavior of optical spectrums emitted by atoms. When white light is sent through a spectrum, each color corresponds to a different band of frequencies. If the atom if one element are stimulated by heat or high voltage they will emit not an entire spectrum of radiation but only certain colored lines corresponding to certain definite ... frequencies of light characteristic of that element. One year later, Heisenberg presented his atomic "core ... separate U-235. Heisenberg wrote two papers for each subject. Both papers regarding separa...
