A dark line in a spectrum, also known as an absorption line, represents a specific wavelength of light that has been absorbed by a substance between the source of light and the observer. The presence of dark lines in a spectrum can provide information about the composition and properties of the absorbing material.
Dark lines in the spectrum were named after German physicist Joseph von Fraunhofer, who first systematically studied them. They are commonly known as Fraunhofer lines and are formed when certain chemical elements absorb specific wavelengths of light, creating dark bands in the spectrum.
Dark lines in an absorption spectrum are caused by material existing between the source of light and the observation point. This material can absorb light from the source at specific energies corresponding to the excitation energies of the molecules, atoms, or ions making up the material.
The color of a mercury spectrum line with a wavelength of 576.96 nanometers is green.
A continuous spectrum contains an unbroken range of wavelengths, such as the colors of a rainbow. A line spectrum consists of discrete, individual lines at specific wavelengths, typically seen when elements emit light at specific energies.
dark-line spectrum...
The dark line spectrum was first observed by Joseph von Fraunhofer in 1814 during his study of the Sun's spectrum. These dark lines are now known as Fraunhofer lines and are caused by absorption of specific wavelengths of light by various elements in the Sun's atmosphere.
No, an absorption spectrum and a bright line spectrum are not the same. An absorption spectrum is produced when light is absorbed by atoms or molecules, showing dark lines at specific wavelengths. On the other hand, a bright line spectrum is produced when atoms or molecules emit light at specific wavelengths, creating bright lines in the spectrum.

It is unique to a specific atom. The emission spectrum of sodium, for example, has two characteristic lines close together in the yellow part of the spectrum, which cannot be found in any other atom. Each line in a spectrum relates to a change in electron state or level.
An absorption spectrum is typically used to determine the composition of a planet's atmosphere. This type of spectrum shows specific wavelengths of light that are absorbed by different gases in the atmosphere, allowing scientists to identify the presence of specific elements or compounds.
The dark lines reveal the atoms that are associated with the stars atmosphere. The dark lines are atom energy absorption signatures.
Because the band is broken by colorless gaps
A star's dark line spectrum reveals the elements present in its atmosphere. Each dark line corresponds to a specific element that has absorbed light at that particular wavelength, providing a fingerprint of the star's chemical composition. By analyzing these lines, astronomers can determine the types and abundances of elements in the star.
