Bohr's atomic theory

WebThe Bohr model of the atom was proposed by Neil Bohr in 1915. It came into existence with the modification of Rutherford’s model of an atom.

The radio then plays the music for you that is encoded in the waveform of the radiated energy. Figure 1.8.1 : The classical death spiral of an electron around a nucleus.
