WebOct 14, 2010 · Bohr preferred to think of the emitted or absorbed radiation as a wave, rather than as a particle. Bohr’s hesitation in accepting the existence of photons during this period seems to arise from his concern that such a particle conception of light would be irreconcilable with familiar interference phenomena. For example, Bohr writes in 1921, WebJul 26, 2024 · Niels Bohr, a Danish scientist, explained this line spectrum while developing a model for the atom: The Bohr model shows that the electrons in atoms are in orbits of differing energy around the nucleus (think of planets orbiting around the sun).
