Dark line absorption spectrum
A spectral line may be observed either as an emission lineor an absorption line. Which type of line is observed depends on the type of material and its temperature relative to another emission source. An absorption line is produced when photons from a hot, broad spectrum source pass through a cooler material. See more 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. … See more 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 … See more Bands The phrase "spectral lines", when not qualified, usually refers to lines having wavelengths in the visible band of the full electromagnetic spectrum See more • Griem, Hans R.

When a photon has about the right … See more 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 … See more • Absorption spectrum • Atomic spectral line • Bohr model • Electron configuration See more WebThis is called a line absorption spectrum. Therefore, when this light passes through a gas, the gas atoms may absorb certain wavelengths to produce a line absorption spectrum. Black...

The resulting spectrum is known as the absorption … WebApr 11, 2024 · A dark line, or absorption spectrum, consists of a series or pattern of dark lines—missing colors—superimposed upon the continuous spectrum of a source. A bright line, or emission spectrum, appears as a pattern or series of bright lines; it consists of light in which only certain discrete wavelengths are present. (Figure \(\PageIndex{4 ...
WebAn emission line spectrum consists of bright lines on a dark background, while an absorption line spectrum consists of dark lines on a rainbow background. If we say that a material is opaque to ultraviolet light, we mean that it _________. emits ultraviolet light absorbs ultraviolet light transmits ultraviolet light reflects ultraviolet light WebThe meaning of DARK-LINE SPECTRUM is a line spectrum produced by the passage of white light through an ionized gas or vapor.

WebSep 21, 2024 · When we see dark lines in a spectrum, they correspond to certain wavelengths being missing due to absorption by matter (in the form of atoms/molecules) on their way. So the dark line represents “absence of light” in a spectrum, not any particular wavelength (color) of light. What is the bright-line spectrum of an element?
