Rydberg Constant
The Rydberg constant (Ry) is a physical constant that represents the highest wavenumber (inverse wavelength) of any photon in the hydrogen atom's emission spectrum, used to calculate spectral lines.
History/Origin
Named after the Swedish physicist Johannes Rydberg, the Rydberg constant was introduced in the late 19th century as part of Rydberg's formula to describe the spectral lines of hydrogen, significantly advancing atomic physics.
Current Use
The Rydberg constant is used in quantum physics and spectroscopy to determine energy levels of hydrogen and other hydrogen-like atoms, and in calculations involving atomic spectra and quantum mechanics.
Kilogram-Force Centimeter
Kilogram-force centimeter (kgf·cm) is a unit of torque or moment of force, representing the force of one kilogram-force applied at a distance of one centimeter from the pivot point.
History/Origin
The kilogram-force centimeter originated from the use of the kilogram-force as a unit of force in the metric system, combined with the centimeter as a unit of length, primarily used in mechanical and engineering contexts before the widespread adoption of SI units.
Current Use
Today, kgf·cm is largely considered a non-SI unit and is used in certain engineering fields, such as torque measurement in automotive and mechanical applications, but is being gradually replaced by SI units like Newton-meter (Nm).
