Kapeapäästö

Kapeapäästö refers to a narrow emission spectrum, often observed in light sources or atomic emissions. This phenomenon occurs when a substance emits or absorbs light at very specific, discrete wavelengths, as opposed to a continuous spectrum. These specific wavelengths are determined by the energy levels of the atoms or molecules involved. When electrons in an atom transition between energy levels, they emit or absorb photons with energies corresponding precisely to the difference between those levels. This results in a series of sharp lines in the emission or absorption spectrum, each line representing a unique wavelength.

Examples of kapeapäästö can be found in various scientific contexts. The light emitted by gas discharge lamps, such as neon signs or fluorescent lights, often exhibits kapeapäästö. Each element has a unique spectral fingerprint, making spectral analysis a crucial tool in fields like astronomy and chemistry for identifying the composition of stars, nebulae, and unknown substances. The study of these narrow emission lines allows scientists to understand atomic structure and the physical conditions of distant celestial objects.
