Fényer

Fényer is a Hungarian neologism that appears in popular science and science fiction to denote the energy content or energy flux of light. It is not an official term in physics, and its precise definition can vary by author or context.

Origin and form: The word is formed from fény, meaning light, and erő, meaning power, with a nominal suffix. In practice, it functions as a conceptual label rather than a formal quantity.

Relation to established concepts: In physics, light energy is described as radiant energy, radiant flux and irradiance, among other quantities. The term “fényer” is sometimes used informally as a shorthand for the energy carried by a light beam or for its energy flux, but it has no standard, universally accepted meaning.

Measurement and values: When used, a given light beam’s “fényer” would correspond roughly to irradiance (power per unit area, measured in watts per square meter) or, in some contexts, to radiant energy over a time interval. Photodetectors and radiometers are used to measure the underlying quantities.

Uses and context: In education, popular science writing and fiction, “fényer” can help illustrate how much energy light delivers to a surface, how solar cells convert light, or how lasers interact with matter.
