Színképelemzés

Színképelemzés, also known as spectral analysis, is a technique used to determine the specific wavelengths of light that a substance emits or absorbs. This pattern of wavelengths, known as a spectrum, acts like a unique fingerprint for the substance. By examining the spectrum, scientists can identify the chemical composition of the material. This principle is based on the fact that different elements and molecules interact with light in distinct ways. When light passes through a substance, certain wavelengths are absorbed, while others are transmitted or emitted. The color spectrum we observe is a result of these interactions.

The process involves passing light through a prism or diffraction grating, which separates the light into its constituent wavelengths. A detector then measures the intensity of light at each wavelength. Emission spectra are produced when a substance emits light, typically when heated or excited. Absorption spectra are formed when light passes through a substance, and specific wavelengths are absorbed. Színképelemzés has wide-ranging applications across various scientific fields. It is used in astronomy to analyze the composition of stars and galaxies, in chemistry for identifying unknown compounds, and in environmental science to detect pollutants. It also plays a role in quality control for manufactured goods and in medical diagnostics.
