Johannes Robert Rydberg (born November 8, 1854 in Halmstad , † December 28, 1919 in Lund ), also known as Janne Rydberg , was a Swedish physicist and is mainly known for setting up the Rydberg formula . It indicates the wavelength of electromagnetic radiation that an electron in an atom emits when transitioning between two energy levels.
A physical constant , the Rydberg constant , is named after him, from which the Rydberg frequency and the Rydberg energy are derived. Excited atoms with very high values of the principal quantum number n are called Rydberg atoms ; dealing with such Rydberg states is sometimes called "Rydberg physics". In recognition of his achievements, a crater on the moon and the asteroid (10506) Rydberg are named after him.
He spent his entire academic life at Lund University . On June 26, 1919, he was elected a foreign member of the Royal Society .
