Optical emissions especially the balmer lines
WebIn a systematic study of the Fe ii spectrum for quasars from the bright quasar survey (BQS), Boroson & Green found that the Fe ii width is similar to that of Balmer lines (see also Zhang et al. 2006), while Véron-Cetty et al. (2004, hereafter VJV04) also identified a number of forbidden optical Fe ii lines from the narrow emission line region ... WebOct 26, 2015 · The Balmer series is the name given to a series of spectral emission lines of the hydrogen atom that result from electron transitions from higher levels down to the energy level with principal quantum number #2#.. There are four transitions that are visible in the optical waveband that are empirically given by the Balmer formula. The …

A hydrogen atom consists of an electron orbiting its nucleus. The electromagnetic force between the electron and the nuclear proton leads to a set of quantum states for the electron, each with its own energy. These states were visualized by the Bohr model of the hydrogen atom as being distinct orbits around the nucleus. Each energy level, or electron shell, or orbit, is designated … WebDec 16, 2011 · The Balmer lines are the most well known and observed emission lines in astronomy, both being strong lines in the optical and ubiquitous as they arise from recombination to the n = 2 level of the most common element, hydrogen.
WebH-alpha ( Hα) is a deep-red visible spectral line of the hydrogen atom with a wavelength of 656.28 nm in air and 656.46 nm in vacuum. It is the first spectral line in the Balmer series and is emitted when an electron falls from a hydrogen atom's third- …
