The term “ far from sources ” refers to how far from the source ( moving at the speed of light ) any portion of the outward-moving EM field is located, by the time that source currents are changed by the varying source potential, and the source has therefore begun to generate an outwardly moving EM field of a different phase.

In thermodynamics, the term exothermic (" outside heating ") describes a process or reaction that releases energy from the system, usually in the form of heat, but also in the form of light ( e. g. a spark, flame, or explosion ), electricity ( e. g. a battery ), or sound ( e. g. burning hydrogen ).

In 1926 the chemist Gilbert N. Lewis coined the name photon for these particles, and after 1927, when Arthur H. Compton won the Nobel Prize for his scattering studies, most scientists accepted the validity that quanta of light have an independent existence, and Lewis ' term photon for light quanta was accepted.

Regional rail does not exist in this sense in the United States, so the term " regional rail " has become synonymous with commuter rail there, although the two are more clearly defined in Europe.

In Germany the term Stadtbahn ( to be distinguished from S-Bahn, which stands for Stadtschnellbahn ) was used to describe the concept, and many in the UMTA ( now called the Federal Transit Administration ) wanted to adopt the direct translation, which is city rail ( the Norwegian term, bybane, means the same ).

However, the UMTA finally adopted the term light rail instead.

Light rail is similar to the British English term light railway, long used to distinguish railway operations carried out under a less rigorous set of regulation using lighter equipment at lower speeds from mainline railways.

The use of the generic term light rail avoids some serious incompatibilities in British and American English.

However, in Europe, the term light rail is increasingly being used to describe any rapid transit system with a fairly lower frequency or shorter trains compared to heavier mass rapid systems such as the London Underground or the Mass Rapid Transit in Singapore.
