Rydberg Constant: 10,973,731.6 per meter

The units for Rydberg's constant are [L-1].

The dimensional formula of Rydberg's constant is [M ^{-1} L ^{-1} T ^{-1}], where M is mass, L is length, and T is time. This constant is used to calculate the wavelengths of emitted photons in hydrogen atoms and is approximately equal to 1.097 x 10^7 m^{-1}.

The Rydberg constant is a fundamental physical constant that appears in the equations describing the behavior of electrons in atoms. It is used to calculate the wavelengths of spectral lines emitted or absorbed by hydrogen atoms, helping to understand their energy levels and transitions. The Rydberg constant also plays a key role in the development of atomic theory and the empirical observation of atomic spectra.

The units are m-1 or per metre.
