How is an atomic line spectrum produced
WebThere are three common mechanisms for the production of X-rays: the acceleration of a charged particle, atomic transitions between discrete energy levels, and the radioactive decay of some atomic nuclei. Each mechanism leads to a characteristic spectrum of X-ray radiation. In the theory of classical electromagnetism, accelerating electric charges emit … WebThe theoretical basis of atomic spectroscopy is the transition of electrons between energy levels in atoms. For example, if an electron in a hydrogen atom makes a transition from the n = 3 to the n = 2 shell, the atom emits a photon with a wavelength. λ = c f = h · c h · f = h c Δ E = h c E 3 − E 2, 8.36. where Δ E = E 3 − E 2 is ...

WebThe classical example of a continuous spectrum, from which the name is derived, is the part of the spectrum of the light emitted by excited atoms of hydrogen that is due to free electrons becoming bound to a hydrogen ion and emitting photons, which are smoothly spread over a wide range of wavelengths, in contrast to the discrete lines due to … Web5 sep. 2024 · – A line spectrum is an emission spectrum that has sharp lines produced by specific frequencies of light. – It is produced by excited atoms and ions as they fall back to a lower energy level. – Different elements have different line spectra so they can be used to identify. evidence for the existence of electrons.
