Spektrianalüüsiks refers to the process of spectral analysis, a technique used in various scientific fields to examine the interaction between matter and electromagnetic radiation. This interaction is dependent on the wavelengths of the radiation, allowing scientists to gain insights into the composition and properties of substances.

The fundamental principle behind spectral analysis lies in the fact that different elements and molecules absorb and emit electromagnetic radiation at specific, characteristic wavelengths. When radiation passes through a sample, some wavelengths are absorbed by the sample's components, while others are transmitted or reflected. Similarly, when a sample is excited, it emits radiation at distinct wavelengths.

Spectrometers are the instruments used to perform spectral analysis. These devices measure the intensity of radiation at different wavelengths, producing a spectrum. This spectrum acts like a unique fingerprint for the substance being analyzed. By comparing the observed spectrum to known spectral databases, scientists can identify the elements or compounds present in a sample.

Applications of spectral analysis are widespread. In astronomy, it is used to determine the chemical composition of stars and planets. In chemistry, it aids in identifying unknown substances and quantifying the amounts of different components in a mixture. Environmental monitoring utilizes spectral analysis to detect pollutants in air and water. Furthermore, it finds use in medicine for diagnostic purposes and in materials science for quality control. The versatility and precision of spectral analysis make it an indispensable tool in modern science and technology.
