Spectral analysis is a procedure in which a light source is shone through a lens to reveal its components. Light created by different methods have different spectral components, which act like a fingerprint. For example, if you examine the spectrum of a distant star, the different wavelengths will show you what different elements comprise that star.
At a more detailed scientific level, the individual lines are determined by the amount of energy lost by a particular atom's electrons as they move between energy levels. Each energy level of an atom's electron shell is characteristic to that atom. When an electron moves from a higher energy level to a lower one, there is a release of energy in the form of a photon, and that photon's wavelength is determined by the amount of energy change, resulting in a spectrographic line characteristic to that atom.

The spectral type of a star measure?
The spectral type of a star is what measures its chemical composition. The visible light that bounces off of it can be used to determine the composition.
Why do astronomers say that the spectral lines produced by an element are like fingerprints?
The energy levels of an atom are the distinctive property of that atom. The difference in energy levels determine the amount of light that could be emitted or absorbed. There is no same energy level difference from one atom to another, therefore spectral lines are referred to as an "atom's fingerprint". The spectral lines make atoms unique, just as fingerprints make people unique, no two humans have the same fingerprints.
How do astronomers determine the composition of distant celestial objects?
Spectroscopy is the systematic study of spectra and spectral lines. Spectral lines are used to provide evidence about the chemical composition of distant objects. So the answer to your question is through spectroscopy.. not spectrometry like the previous editor posted.
Relate the stellar temperature to the classification of a star?
Stellar classification is based on the analysis of light from stars. The temperature from the photosphere of the star effects the amount and types of ions and this is used classifying the star.
What was the optical analysis system used for?
It dont matter
What is used to help humans determine temperature of the stars?
spectral analysis
What used to help humans determine the temperature of stars?
spectral analysis
What is an emission spectra used for?
The emission spectrum can be used to determine the composition of a material
The spectral type of a star measure?
The spectral type of a star is what measures its chemical composition. The visible light that bounces off of it can be used to determine the composition.
What is a line spectrum used for?
The line spectrum is usually used to sort out the atomic fingerprint as the gas emit light at very specific frequencies when exposed to the electromagnetic waves. The electromagnetic waves are usually displayed in form of the spectral lines.
What tool is most likely to be used by scientist to separate a beam of white light into different colors?
A Prism can be used to break light up into its constituent spectral colors.
Why is light an important tool used in astronomy?
Stars are the sources of light. If they did not emit light, there would be no stars and thus no astronomy.
What is Spectral DNC used for?
Spectral DNC is used to prevent hair loss and restore hair growth. This topical hair loss product is produced by DS Laboratories. Spectral DNC's active ingredients include Minoxidil and Aminexil.
What are the two most important uses of Argon?
Argon is used in light bulbs and many sources of light
What is brand analysis used for?
Brand analysis is the procedure on comprehensively collecting qualitative and quantitative information from all available sources and assessing it to determine the state and perception of a particular brand. Brand analysis is used alongside competitor analysis and target analysis in order to make decisions which will maximise the financial benefit of the brand without sacrificing reputation.
What is the purpose of the slit in the spectroscope?
The purpose of the slit in the spectroscope is to regulate the amount of light that comes in. Without the slit, light would come from various angles.
What are the two sources of light used in Fiber Optic Cables?
laser and led
