Bohr Model of the Hydrogen Atom: Postulates, Limitations

WebBased on empirical data measured by Anders Angstrom, Johann Balmer (1825- 1898) was a Swiss mathematician who developed an equation for computing the wavelengths of the line spectra. It needs to be emphasized that although this equation could account for the line spectra it was based on empirical (experimental) data. WebThe Bohr model was based on the following assumptions.
