quantum theory

Definitions

Astronomy

  • Theory developed by Danish physicist Neils Bohr (1885–1962) which states that at the smallest scale, energy exists in discontinuous ‘lumps’ or quanta rather than being infinitely divisible. Thus lines in the spectra of stars mark the quantum of energy separating two different energy levels of a particular electron in an atom, the energy of the transition being given by h, Planck’s constant, multiplied by the frequency of the spectral line.
