többhullámhosszuságú

többhullámhosszuságú is a Hungarian adjective that translates to "multispectral" or "multi-wavelength" in English. It describes something that operates or is observed across multiple distinct ranges of wavelengths, typically within the electromagnetic spectrum.

In remote sensing and astronomy, the term "többhullámhosszuságú" is frequently used. A többhullámhosszuságú sensor, for instance, collects data in several different spectral bands, such as visible light, infrared, and ultraviolet. This allows for a more comprehensive analysis of an object or phenomenon compared to sensors that operate in a single band. By examining how an object reflects or emits radiation across these different wavelengths, scientists can infer properties like its composition, temperature, and physical state.

For example, a többhullámhosszuságú satellite imagery system can differentiate between various types of vegetation, identify mineral deposits, or detect atmospheric pollution by analyzing the spectral signatures of the Earth's surface. Similarly, astronomers use többhullámhosszuságú telescopes to study celestial bodies, gathering information from radio waves to gamma rays, which reveals different physical processes occurring in stars, galaxies, and other cosmic objects. The principle behind "többhullámhosszuságú" is that different physical phenomena manifest uniquely at different wavelengths, and observing across multiple wavelengths provides a richer, more complete understanding.
