Everything about Johannes Rydberg totally explained
Johannes Robert Rydberg, (‘Janne’ to his friends), (
November 8,
1854 –
December 28,
1919), was a
Swedish physicist mainly known for devising the
Rydberg formula, in 1888, which is used to predict the
wavelengths of
photons (of
light and other
electromagnetic radiation) emitted by changes in the energy level of an
electron in an
atom.
The
physical constant known as the
Rydberg constant is named after him, as is the
Rydberg unit. Excited atoms with very high values of the
principal quantum number, represented by
n in the
Rydberg formula, are called
Rydberg atoms, and a
crater on the moon is also named
Rydberg in his honour. Rydberg's faith that spectral studies could assist in a theoretical understanding of the atom and its chemical properties was justified in 1913 by the work of Niels Bohr (see hydrogen spectrum). An important spectroscopic constant based on a hypothetical atom of infinite mass is called the Rydberg (R) in his honor.
He was active at
Lund University,
Sweden, for all of his working life.
