Emissionslinjespectrum
Emissionslinjespectrum, also known as an emission spectrum, is a set of discrete wavelengths of electromagnetic radiation that are emitted by a substance. When an atom or molecule absorbs energy, its electrons can be excited to higher energy levels. As these electrons return to their lower energy ground state, they release the excess energy in the form of photons. The energy of each photon corresponds to a specific wavelength of light, and the collection of these wavelengths forms the emission spectrum.
Each element has a unique emission spectrum, acting as a fingerprint that can be used for identification.
Emission spectra are observed when a substance is excited, such as by heating it to a high
The study of emission spectra is fundamental in various scientific fields, including astrophysics for determining the
