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.
Therm (Ec)
The therm (EC) is a unit of energy used primarily in the measurement of natural gas and heating energy, equivalent to 100,000 British thermal units (BTUs).
History/Origin
The therm originated in the early 19th century as a practical unit for measuring large quantities of heat energy, especially in the gas industry, and has been standardized in various regions for energy billing and calculations.
Current Use
Today, the therm (EC) is used mainly in the natural gas industry and energy sectors to quantify heat energy consumption, although it has largely been supplemented or replaced by SI units like joules and kilowatt-hours in many regions.
