Spektrum

Spektrum is the spelling used in German and Dutch for the concept of spectrum; in English, the corresponding term is spectrum. The word derives from the Greek spektron and is used across science, technology, and culture to denote a range or distribution of something, such as wavelengths or energies.

In science, a spectrum represents the distribution of a physical quantity as a function of a variable like wavelength, frequency, or energy. The electromagnetic spectrum covers radio waves through visible light to gamma rays. Spectra can be continuous or discrete, and spectral data help identify materials, determine temperatures, measure motion, and analyze chemical composition. Common methods include emission spectroscopy, absorption spectroscopy, and mass spectroscopy, among others.

In technology and consumer electronics, Spektrum is a brand name associated with radio control systems for hobbyist vehicles, produced by Horizon Hobby. Spektrum products include transmitters, receivers, and related accessories, and the systems are known for digital control protocols and compatibility with telemetry features. The brand is widely used in RC airplanes, cars, boats, and drones.

In other contexts, Spektrum appears in media and language use, such as Spektrum der Wissenschaft, a German science magazine. The term is also used as the standard transliteration of the word spectrum in German and Dutch contexts, reflecting its broad scientific and cultural relevance.
