spektrilised

Spektrilised is an Estonian adjective meaning spectral; it is used to describe phenomena, measurements, and methods related to a spectrum—the distribution of a quantity across wavelengths or frequencies. In technical writing, spektrilised is the analogue of the English term spectral and is widely used in physics, chemistry, astronomy, and signal processing.

Applications include spectroscopy, which analyzes how matter absorbs or emits radiation across different wavelengths to determine composition and properties; astronomical spectroscopy, which identifies elements and measures motion via spectral lines and redshift; and spectral imaging and color science, which use the distribution of light across wavelengths to characterize materials or scenes. In signal processing, spectral analysis examines the frequency content of signals, often using Fourier transforms.

Key concepts associated with spektrilised phenomena include the spectrum, spectral resolution, spectral density, and spectral lines. A spectrum is commonly plotted as intensity or power versus wavelength or frequency. The term also appears in discussions of lighting and color, where the spectral power distribution defines color appearance. As a technical term, spektrilised describes properties or techniques that depend on, or reveal, a spectrum.
