WebA 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 5.11 shows an ... WebMar 11, 2024 · The electromagnetic spectrum is a continuous distribution of wavelengths ranging from ultraviolet to infrared radiation. A dark-line spectrum, or absorption spectrum, is exactly the opposite — instead of bright lines at each wavelength on a dark background, an absorption spectrum has dark lines at the corresponding wavelengths …

WebDark lines in an absorption spectrum show the wavelengths a particular element can absorb. For example, if an element X has 5 lines between 600 and 700 nm, it shows that … 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.
