How do different scientists spectra to figure out the composition of a star's outer layer?
The color of the light radiated by the spectra can show the internal composition as well as the gases burning on the outer layer. Red stars are colder and blue stars are hotter.
What is a stellar spectra?
A stellar spectrum is the light emitted by a star.
Is phosphine show inversion spectra?
yes
What can you infer about a star that exhibits a red shift in its spectra?
It is moving away at a significant speed.
The spectra of interstellar gas clouds show that they have the same basic composition as?
stars
What information can astronomers obtain by studying the spectra from stars?
They can obtain information about what elements are in the star; about the star's temperature; about whether the star is moving towards us or away from us; and partial information about the star's rotation.
What is astronomical ccd?
It is a central conical device- used to help find the stellar spectra of a star or planet.
Show diagram of rear brakes for 2003 Kia Spectra?
Sorry, we can't do diagrams.
Why is it that different light sources have different types of spectra?
Different atoms have a different number of electrons. This is why they show different spectra.
Suppose you want to know the chemical composition of a distant star Which piece of information is most useful to you?
A telescope, whose light output would be sent through a spectral analysis machine of some type. That analysis of the emission spectra of the star would be compared to the known spectra of the elements to find the composition of the star.
How do scientists use different spectra to figure out the composition of the stars outer layer?
Different chemical elements emit (or absorb) certain specific frequencies of light. When the light from a star is split in to it's rainbow spectrum of light, certain parts of the spectrum will be black (in absorption spectra) or brighter (in emission spectra). By comparing these lines to the known emission and absorption spectra of elements, the composition of a stars atmosphere can be determined.
What is the plural of the word spectra?
Spectra is the plural of spectrum. You could discuss the spectrum generated by an element in a star, and comparing more than one element, you would be comparing spectra. (Latin -um words form plurals like this, so you cannot refer to them as spectrums. Another example is datum, singular, and data, plural.)
