Web30.33. We see that Bohr’s theory of the hydrogen atom answers the question as to why this previously known formula describes the hydrogen spectrum. It is because the energy levels are proportional to 1 / n 2, where n is a non-negative integer. A downward transition releases energy, and so n i must be greater than n f.

WebSep 20, 2024 · Bohr's Atomic Model. Following the discoveries of hydrogen emission spectra and the photoelectric effect, the Danish physicist Niels Bohr (1885-1962) proposed a new model of the atom in 1915. Bohr proposed that electrons do not radiate energy as they orbit the nucleus, but exist in states of constant energy that he called stationary … WebThe reason is that there is a consistency condition: the level-spacing must be such that photon emission must be possible at the classical frequencies (integer multiples of the orbital frequency). This is Bohr's correspondence principle, and it really is right for the energy levels to leading order in $\hbar$. Read my answer. $\endgroup$ –
