Dark lines in an absorption spectrum are called absorption lines. These lines correspond to wavelengths of light that have been absorbed by specific elements or molecules in the sample being analyzed. They appear as dips or gaps in the spectrum where less light is detected.

What are dark lines in a stellar spectrum called?
The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star. ================================ Fraunhofer's spectral lines.
What is the difference between absorption and emission spectrum?
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
How can you tell the absorption lines in the photographic spectrum?
Absorption lines in a photographic spectrum appear as dark lines where specific wavelengths of light are absorbed by elements in a celestial object. These lines indicate the presence of elements in the object's atmosphere and can be identified by comparing their positions with known spectral lines of elements on Earth.
What are the dark lines in a stellar spectrum are called?
Fraunhofer realised that some of these dark lines were at the same position in effect called the Zeeman effect can also cause splitting of the spectral lines.
Can the pattern of dark lines recorded by a spectrograph be used to identify the elements that are in the stars atmosphere?
Yes, the pattern of dark lines in a stellar spectrum, known as absorption lines, can be used to identify the elements present in a star's atmosphere. Each element produces a unique set of absorption lines at specific wavelengths, allowing astronomers to determine which elements are present in the star. This process is known as spectroscopy and is an essential tool in studying the composition of stars.
What are dark lines in a stellar spectrum called?
The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star. ================================ Fraunhofer's spectral lines.
What is a dark line found in a spectrum is called?
A dark line found in a spectrum is called an absorption line. Absorption lines are created when atoms or molecules absorb specific wavelengths of light, resulting in dark lines in the spectrum where that light is missing.
What are the Dark lines that appear in a spectrum of light from a star called?
The dark lines that appear in a spectrum of light from a star are called absorption lines. These lines are caused by the absorption of specific wavelengths of light by elements in the outer atmosphere of the star. Absorption lines help astronomers identify the chemical composition of stars and other celestial objects.
What part of the star is responsible for the dark lines in its spectrum?
The dark lines in a star's spectrum are caused by absorption of specific wavelengths of light by the elements in the star's outer atmosphere. This absorption occurs when the elements in the atmosphere absorb photons of specific energies, leading to the creation of dark absorption lines in the spectrum.
Is an absorption spectrum also called a bright line spectrum?
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.
Narrow lines of colors with no light in between them are called what?
Narrow lines of colors with no light in between them are called dark lines. They are typically seen in the spectrum of light when certain wavelengths are absorbed or blocked.
What are some comparisons with a absorption spectrum and a continuous spectrum?
An absorption spectrum shows dark lines at specific wavelengths where light has been absorbed by a substance. A continuous spectrum shows all colors/wavelengths with no gaps, like the rainbow. The main difference is that the absorption spectrum has specific dark lines while the continuous spectrum is smooth and uninterrupted.
What does the presence of dark lines in the solar spectrum mean?
The dark lines represents the absorption of energy at that frequency, E=hf.
What does a star's dark-line spectrum reveal?
The dark lines reveal the atoms that are associated with the stars atmosphere. The dark lines are atom energy absorption signatures.
What were dark lines in the spectrum named for?
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.
How can you Distinguish absorption spectrum from emission spectrum?
An absorption spectrum shows the wavelengths of light absorbed by a substance, appearing as dark lines on a bright background. An emission spectrum shows the wavelengths of light emitted by a substance, appearing as bright lines on a dark background. In other words, absorption involves light being absorbed by the substance, while emission involves light being emitted by the substance.
Fraunhofer lines in the solar spectrum are actually?
Fraunhofer lines are dark absorption lines in the solar spectrum caused by specific elements absorbing certain wavelengths of light. These lines help astronomers identify the chemical composition of the Sun and other stars because each element absorbs light at characteristic wavelengths, leaving dark lines in the spectrum.
