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 ...
WebThe gaps (dark lines) in an absorption spectrum are formed because light of the specific energy (or wavelength, if you prefer) in the dark lines is absorbed by the atoms in a gas. This process is called photo-excitation. WebThe dark lines are the parts of the spectrum where the electrons absorb light photons, hence, there is absence of light at these parts. The remaining colored parts of the spectrum represent the parts of the incident light …
