What were dark lines in the spectrum named for?
Dark lines especially in solar spectrum have been named as Fraunhofer lines. These line are good examples for line absorption spectrum
What is s band spectrum?
Band spectrum is the spectrum given by the molecules. It consists of series of closely spaced lines known as bands separated by the dark spaces.
The lines at the ultraviolet end of the hydrogen spectrum are known as the lyman series wich electron transitions within an atom are responsible for these lines?
The series of lines in an emission spectrum caused by electrons falling from energy level 2 or higher (n=2 or more) back down to energy level 1 (n=1) is called the Lyman series. These emission lines are in the ultra-violet region of the spectrum.
Why elements give line spectrum?
Because the spectra of elements is determined by the energy of transitions of electrons between two allowed quantum states. Since these energy differences can have only certain specified values, the spectrum consists of lines: The spectrum frequency values intermediate between the lines do not correspond to transitions between any two allowed quantum states and therefore do not appear in the spectrum
Starlight passing through a device for separating light produces a display of colors and lines called a?
Spectrum
What causes spectra lines?
Absorption of energy at atom energy levels cause the line spectrum.
What were dark lines in the spectrum named for?
Dark lines especially in solar spectrum have been named as Fraunhofer lines. These line are good examples for line absorption spectrum
What causes lines in a line spectrum?
Wavelengths of absorbed or emitted photons Every line in a line spectrum is caused by a transition, from one quantum state to another quantum state, involving electrons.
What part of the star is responsible for the dark lines in its spectrum?
Atoms in the atmosphere of the star is responsible for the dark lines in its spectrum.
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.
Dark lines in an absorption spectrum are called?
Absorption lines
Does the helium spectrum have twice as many lines as the hydrogen spectrum?
No. In vacuum(i.e.no continuum lowering), both have an infinite number of lines in the spectrum, hence the question makes no sense.
Continuous spectrum with dark lines where light is absorbed?
dark-line spectrum...
How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
An emission spectrum depend on electrons transition in the atom of a chemical element; and elements are different.Absorption spectrum is based on the different absorption pics of different molecules, depending on the frequency of radiation.Spectral methods are largely used in analytical chemistry.
What is the continuous spectrum of a star?
A continous spectrum hasn't discrete gaps between lines.
The composition of a star can be identified by?
the lines in its spectrum
What are the Dark lines that appear in a spectrum of light from a star called?
absorption lines! :)
