Bohr Model of the Hydrogen Atom

The video explores the concept of energy quantization, starting with Einstein's extension of Planck's idea to electromagnetic radiation. It delves into Bohr's model of the hydrogen atom, explaining how electrons occupy quantized energy levels and transition between them by absorbing or emitting photons. The Rydberg equation is introduced to predict photon wavelengths during these transitions. The video also discusses the Lyman and Balmer series of electron transitions and how emission spectra serve as unique fingerprints for elements, aiding in the analysis of cosmic compositions.

What problem was Niels Bohr addressing with his model of the hydrogen atom?
