The absorption spectrum shows the specific wavelengths of light that are absorbed by a material, indicating the energy levels of electrons in the substance. By analyzing the absorption spectrum, scientists can identify the chemical composition of the material and understand its electronic structure.
What else can I help you with?
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 can a star's spectrum tell us?
scientists can tell the stars composition and temperature from its spectrum. Hope tht helps :]
When the absorption lines of a galaxy shifts toward the blue end of the spectrum it means that that the galaxy?
It means the heading towards us, red means it is moving away from us.
What conditions lead you to see an absorption line spectrum from a cloud of gas in interstellar space?
The actual presence of the gas cloud's contents will absorb certain wavelengths of Light, preventing the passage of certain photons through the cloud, that results in that Light not reaching us - producing a blank line in the observed spectrum.
Spectrum gives the what of the star's gases?
Spectrum gives information about the composition of a star's gases by breaking down the incoming radiation into its constituent wavelengths. This information helps astronomers determine the elements present in the star's atmosphere and its temperature.

Why might scientists mainly astronomers study the color of metals in a flame?
The colours with which an element (metal or other) burns in a flame are the same colours which are absorbed by that element in the sun's spectrum. The colours are very specific to each element and show up as distinct black lines in the solar spectrum. By studying the spectrum it is possible to tell what elements are in the sun [or star] and also their relative abundance.If a star is moving away from us absorption lines are red-shifted [move towards the red end of the spectrum]. The faster the star is moving away, the greater the red-shift. Also, as Hubble discovered, the greater the red-shift, the further away the star is. So the red shift in the absorption spectrum is a measure of not only how fast the star is receding from us but also how far it is. This allows us to tell whether two stars which are apparently in the same direction are actually close together or simply a coincidental alignment of their lines of sight.
Figure 10.1 shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis Why are they different?
The absorption spectrum shows which wave lengths are absorbed in each individual type of chlorophyll. The action spectrum shows which wavelengths of light are most effective for photosynthesis.
When the absorption lines of a galaxy shifts toward the blue end of the spectrum it means that that the galaxy?
It means the heading towards us, red means it is moving away from us.
When the absorption line of a galaxy shift toward the blue end of the spectrum it means that the galaxy is?
It means the heading towards us, red means it is moving away from us.
How can spectrum tell us if an object is reflecting blue light from a star?
how can you tell if an object is reflecting blue light from a star
How are absorption and emission lines produced in a stellar spectrum What information might absorption lines in the spectrum of a star reveal about a cloud of cool gas lying between us and the star?
Absorption lines are produced when elements in the outer layers of a star absorb specific wavelengths of light, leading to dark lines in the spectrum. These lines indicate the presence of certain chemical elements in the star's atmosphere. Absorption lines from a cool gas cloud between a star and Earth can reveal the composition, density, and temperature of the cloud, providing valuable information about the interstellar medium.
Can you show us what it looks like?
as soon as you tell us what it is.

How can you tell that some galaxies are far away and moving rapidly towards us?
You can tell by the blueshift in the spectrum; the only reasonable explanation for this blueshift is the Doppler effect. - Please note that most galaxies are moving away from us, not towards us.
