Johannes Rydberg, more known as
Janne Rydberg, (
1854 -
1919) was a
Swedish physicist mostly known for creating the
Rydberg formula, which is used to predict which
wavelengths that
photons (i.e.
light) emitted from shifts in the energy level of a certain
electron around a certain
atomic nucleus will have. The
physical constant known as the
Rydberg constant is named after him.
He was active at Lund University for all of his life.
