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.
Megajoule
A megajoule (MJ) is a unit of energy equal to one million joules.
History/Origin
The megajoule was introduced as part of the metric system to measure large amounts of energy, especially in scientific and engineering contexts, aligning with the SI units established in the 20th century.
Current Use
The megajoule is used in fields such as physics, engineering, and energy industries to quantify large energy quantities, including in energy production, consumption, and scientific research.
