Definition
  1. Proper noun:
    • James Franck: A German-born American physicist who, with Gustav Hertz, conducted a pivotal electron scattering experiment. This experiment provided crucial evidence for the existence of quantized, stationary energy states in atoms, a fundamental concept postulated by Niels Bohr in quantum theory.
Usage Examples
  • Proper noun:
    • The Franck-Hertz experiment, conducted by James Franck and Gustav Hertz, is a cornerstone of modern physics education.
    • James Franck was awarded the Nobel Prize in Physics in 1925 for his work on the laws governing the impact of an electron upon an atom.
Advanced Usage
  • "Franck-Condon principle": A fundamental rule in molecular spectroscopy concerning the intensity of vibrational transitions, named in part for James Franck's contributions to quantum mechanics.
    • The Franck-Condon principle explains why certain vibrational bands in a spectrum are more intense than others.
Variants and Related Words
  • Franck-Hertz experiment (noun phrase): The landmark experiment demonstrating quantized atomic energy levels.
    • Undergraduate physics labs often recreate the Franck-Hertz experiment.
Synonyms
  • Physicist: A scientist who specializes in physics.
  • Nobel laureate: A person who has been awarded a Nobel Prize.
Noun
  1. United States physicist (born in Germany) who with Gustav Hertz performed an electron scattering experiment that proved the existence of the stationary energy states postulated by Niels Bohr (1882-1964)
