Photon intensity

WebBohr's model of hydrogen is based on the nonclassical assumption that electrons travel in specific shells, or orbits, around the nucleus. Bohr explained the hydrogen spectrum in terms of electrons absorbing and emitting photons to change energy levels, where the photon energy is. Bohr's model does not work for systems with more than one electron. WebAug 14, 2024 · This is a very important result. You can increase the intensity of the radiation by either increasing the number of photons in it or increasing energy of each photon, or both. As for option (C), if you increase energy of each photon but decrease the number of photons emitted by the source per unit time by the same factor then the intensity will ...
