The emission spectrum of a star is the spectrum of frequencies for emitted electromagnetic radiation during the transition of an atom's electrons from a high-energy state to a low-energy state. The emission spectrum can differ depending on the temperature and composition of the star.

∙ 8y agoEmission spectra tell us about the elements in the surface layers of the star. They can also tell us the star's relative motion (each element has a characteristic spectrum, so how much, and in which direction, the lines are shifted tells us how quickly the star is moving towards or away from us).

Which type of spectrum is associated with the radiation of most stars?
absorption spectrum
Is an atomic emission spectrum a continuous range of colors?
No. Atomic emission spectrum is non-contiuous and it is named as line spectrum.
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.
If we would see a fifth line in the Balmer series emission spectrum. Calculate the wavelength associated with the fifth line?
m lmn ?,
Which of the following describes a spectrum apex?
A range of wavelenghs of frequencies of electromagnetic raditation
Which type of spectrum is associated with the radiation of most stars?
absorption spectrum
How elements of stars are detected?
The emission spectrum of each element has characteristic lines for each element. Analyzing the spectrum of a star, you can figure out what elements are present, and also get an estimate on how much there is of each element. For more information, check the Wikipedia article on "emission spectrum".
Is an atomic emission spectrum a continuous range of colors?
No. Atomic emission spectrum is non-contiuous and it is named as line spectrum.
How you use a spectrometer to help us determine what stars and planets are made of?
Stars and planets are made up of many different atoms. When scientists pass the light coming from the star or planet through the spectrometer they get an emission spectrum. We can compare this emission spectrum to a situation where many people have put their fingerprints in the same spot. The scientist is like a police officer that has to sort them all out. To do this they analyze the emission spectrum to see which atom's individual light fingerprints are in there. In this way, they can use the light from stars and planets to find out what the star or planet is made of.
What is a flame tested used for?
To identify an unknown sample by its emission spectrum
Is it possible for two metals to have the same emission spectrum?
No. It is not possible for two metals to have the same emission spectrum. For metals to have the same emission spectrum, they would need for their electrons to have duplicate orbitals. That would be impossible due to the exclusion principle.
Explain the difference between the continuous spectrum of white light and the atomic emission spectrum of an element?
The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.
An emission spectrum can be used to?
Identify elements
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 do astronimers determine the composition of a star?
The chemical composition of stars is determined by the emission lines present in the light from stars. The emission lines are characteristic of a given element. However, because of the Doppler effect and the numerous emission lines of some elements, this technique can be more difficult in practice than it appears.
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 colors of visible light are found in the emission spectrum of hydrogen?
Red, blue, green, and violet are found in the emission spectrum of hydrogen.
