Convert Attojoule to Rydberg constant
Attojoule
The attojoule (aJ) is a unit of energy in the International System of Units (SI). It is equal to one quintillionth of a joule (0.000000000000000001 J). The attojoule is commonly used to measure extremely small amounts of energy, such as the energy content of individual photons.
The attojoule is derived from the joule, which is named after James Prescott Joule, an English physicist. The prefix 'atto-' signifies a factor of one quintillionth, making the attojoule equal to one quintillionth of a joule.
Rydberg constant
The Rydberg constant (Rₕ) is a physical constant related to the energy of photons emitted or absorbed by an electron transitioning between energy levels in an atom. It is used in atomic physics to describe the wavelengths of spectral lines.
The Rydberg constant is named after the Swedish physicist Johannes Rydberg, who developed the Rydberg formula to predict the wavelengths of spectral lines in hydrogen and other elements.
