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 a band spectrum?
A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.
If you wanted determine the temperature of a star what measurements would you make?
Emission Spectrum
What does the absorption spectrum of an atom show?
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
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
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.

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.
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.
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.

Explain why the fluorescence emission spectrum of a polyaromatic molecule in solution mirrors the shape of the absorption spectrum regardless of the excitation frequency?
Generally fluorescence emission spectrum is independent of the excitation wavelength because of the rapid internal conversion from higher energy initial excited states to the lowest vibrational energy level of the excited state
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.
