The Rydberg constant represents the highest wavenumber (inverse wavelength) that can be emitted from an atom in a series of spectral lines. Named after Swedish physicist Johannes Rydberg, it is a fundamental physical constant used to describe atomic spectra, with the value approximately 10,973,731.56816 per meter.
Definition of Electron-voltAn electron-volt (eV) is a unit of energy equal to approximately 1.602 x 10^-19 joules. It is the amount of kinetic energy gained or lost by a single electron when it moves through an electric potential difference of one volt. Electron-volts are commonly used in atomic, nuclear, and particle physics.

Convert 0.5 Ry to eV:
0.5 Ry = 0.5 × 13.6057 eV = 6.80285 eV
The Rydberg Constant to Electron-volt Converter has its roots in the early 20th century, following the work of Johannes Rydberg on atomic spectra. Over time, the importance of quantifying the energy levels of electrons in atoms led to the need for a practical conversion tool between Rydberg units and electron-volts, aiding researchers and students in the field of atomic physics.
Explore the practical applications of converting Rydberg constants to electron-volts in various scientific fields.
Example 1:
