Bohr Model of the Atom and Atomic Spectra - Quantum Physics

Explore the Bohr Model of the Atom and Atomic Spectra in this comprehensive physics lesson. Delve into Niels Bohr's 1905 quantized model for the hydrogen atom, examining its three key tenets: electrons in circular orbits, quantized energy levels, and photon emission/absorption during orbital transitions. Learn how Bohr's model accurately predicted hydrogen's spectral lines but fell short for multi-electron atoms. Discover the formulas for electron energies in hydrogen atoms and calculate energies and wavelengths of absorbed and emitted photons. Examine four common emission spectra series: Lyman, Balmer, Paschen, and Brackett, with a focus on the visible Balmer series. Practice sample calculations and gain a deeper understanding of atomic structure and spectroscopy through clear explanations and practical examples.
