Is an absorption spectrum also called a bright line spectrum?
No, its an absorption spectrum
If a star is moving away from you the absorption lines in its spectrum will?
If a star is moving away from you, the emission lines in its spectrum will be shiftedtoward longer wavelengths/lower frequency/the red end of the spectrum, since theyoriginate on the star itself.But there's no effect on the absorption lines, because those are caused by materialthat's unrelated to the star, and just happens to be in the line of sight between thestar and you.
Which type of spectrum is produced by nebulae consisting of atoms that release photons when electrons jump from high-energy states to lower-energy states?
Emission spectrum is produced by nebulae consisting of atoms that release photons when electrons jump from high-energy states to lower-energy states.
What type of spectrum do we see from the sun?
some of the light from the corona produces a continuous spectrum that lacks absorption lines. however the type is absorption spectrum
What are the Dark lines that appear in a spectrum of light from a star called?
absorption lines! :)
Which type of spectrum is associated with the radiation of most stars?
absorption 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.
How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
How do emission and absorption spectrums tell us about the composition of objects in our universe?
Each chemical element has a specific emission or absorption spectrum.
What is the difference between absorption and emission spectrum?
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
What is the difference between an absorption and an emission spectrum?
Absorption spectrum is a gap in the overall spectrum. It happen when light makes an electron jump to a higher orbital and light energy is absorbed. Emission spectrum is light emitted at particular wavelengths (where the absorption spectrum gaps are). It happens when an electron falls from a higher orbital and emits light energy in doing so.
What is a band spectrum?
A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.
What is band spectrum?
A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.
How can you predicted the absorption spectrum of a solution by looking at it's color?
By looking at its emission spectrum and seing where the black lines are
Image of emission or absorption spectrum of manganese?
This would consist of several series of lines corresponding to the energies of electron transitions. They are bright lines for an emission spectrum and dark for absorbtion.
An emission spectrum of an atom is produced when its electrons are .?
Releasing Energy
What type of spectrum is produced by a filament lamp?
continuous emission
