He made … WebSep 21, 2024 · In 1913, a Danish physicist, Niels Bohr (1885–1962; Nobel Prize in Physics, 1922), proposed a theoretical model for the hydrogen atom that explained its emission spectrum. Bohr’s model required only one assumption: The electron moves around the nucleus in circular orbits that can have only certain allowed radii.

WebSecond, he assumed that the energy of a photon is proportional to its frequency. E = hv. In this equation, h is a constant known as Planck's constant, which is equal to 6.626 x 10-34 J-s. ... Niels Bohr proposed a model for the hydrogen atom that explained the spectrum of the hydrogen atom. WebThe Bohr model provides a theoretical framework for understanding line spectra. If a photon of light is absorbed, its energy (h ν) is transferred to an electron which jumps from a low energy orbit to a high energy orbit, and the absorption spectral lines are correlated to wavelengths associated with the frequency of that light (c= λν ).
