TCE Physics — Level 4

Bohr Model — Flashcards & Quiz

The Bohr model (1913) describes the hydrogen atom as a positive nucleus surrounded by electrons in discrete, quantised circular orbits. TCE Physics Level 4 asks you to calculate transition energies and wavelengths using the hydrogen energy-level formula, identify spectral series (Lyman, Balmer, Paschen), and explain why discrete emission spectra support the quantised energy-level model.
