A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules. These "fingerprints" can be … Se mer Spectral lines are the result of interaction between a quantum system (usually atoms, but sometimes molecules or atomic nuclei) and a single photon. When a photon has about the right amount of energy (which is connected to its … Se mer Strong spectral lines in the visible part of the spectrum often have a unique Fraunhofer line designation, such as K for a line at 393.366 nm … Se mer Bands The phrase "spectral lines", when not qualified, usually refers to lines having wavelengths in the visible band of the full electromagnetic spectrum Se mer • Griem, Hans R. (1997). Principles of Plasma Spectroscopy. Cambridge: University Press. ISBN 0-521-45504-9. • Griem, Hans R. … Se mer There are a number of effects which control spectral line shape. A spectral line extends over a range of frequencies, not a single frequency (i.e., it has a nonzero linewidth). In addition, its center may be shifted from its nominal central wavelength. There … Se mer • Absorption spectrum • Atomic spectral line • Bohr model • Electron configuration • Emission spectrum Se mer Nettetdefinition Atomic spectra When atoms are excited they emit light of certain wavelengths which correspond to different colors. The emitted light can be observed as a series of colored lines with dark spaces in between; this series of colored lines is called a line or atomic spectra. Each element produces a unique set of spectral lines. definition

This equation was hence combined with the Bohr model to analyze the energy that is needed to shift an electron between its initial energy level and final energy levels. ΔE = Rhc ( (1/n f2) – (1/n i2 )) Paschen Series (nf = 3): The series was initially noticed during the years 1908, by ... NettetThe hydrogen spectrum has many series of lines. These lines are named after their discoverers. In 1885, the scientist Balmer showed that if spectral lines are expressed as wavenumber, then the visible lines of … glasses worn by celebrities
