Using his model, Bohr was able to calculate the spectral lines — the lines in the continuous spectrum of light — that the hydrogen atoms would absorb. The Bohr model seemed to work pretty well ...

Derived by English mathematician John Wallis in 1655, the original formula calculates pi as the product of an infinite series of ratios – it has now emerged from a solution of physicist Niels Bohr’s ...

NCERT has explained how Bohr’s model was too simple to account for the following points- It fails to account for the finer details (doublet, that is two closely spaced lines) of the hydrogen ...

Niels Bohr's model of the hydrogen atom—first published 100 years ago and commemorated in a special issue of Nature—is simple, elegant, revolutionary, and wrong. Well, "wrong" isn't exactly ...

Bohr's atomic model was utterly revolutionary when it was presented in 1913 but, although it is still taught in schools, it became obsolete decades ago. However, its creator also developed a much ...

But there was good evidence he was right: the electrons in his model lined up with the regular patterns (spectral series) of light emitted by real hydrogen atoms. Bohr's theory that electrons ...

To this end, a German named Arnold Sommerfeld provided a generalisation of Bohr's model - a correction - to let it explain the Zeeman effect in ionized helium (which is a hydrogen atom with one ...

One hundred years after Niels Bohr published his model of the atom ... energies — explained the frequencies of light emitted by hydrogen as electrons made leaps between orbits.

and this year marks 100 years since the model was first proposed by Danish physicist Niels Bohr. The idea that matter comprises indivisible units dates back to Indian and Greek philosophers.
