What else can I help you with?
The spectrum of a star is called a what?
... a photonic 'fingerprint'. The picture of a star's spectral lines is its photo-spectrograph.
What does a spectograph tell us?
A spectrograph tells us which colors (wavelengths of light) are in a luminous source.
What part of a star is it that astronomers study in order to learn its characteristics of a star?
Astronomers study the spectrum of light emitted by a star to learn about its characteristics. By analyzing the composition of elements, temperature, and density of a star, astronomers can determine its size, age, brightness, and life cycle stage.
How does a spectrograph provide information about stars chemical composition?
A spectrograph breaks down the light from stars into its component colors or wavelengths. Each chemical element absorbs and emits light at specific wavelengths, creating a unique fingerprint called a spectral line. By analyzing the spectral lines in a star's light, scientists can determine its chemical composition.
Can you tell the age of a star?
By analyzing the proportions of hydrogen and helium in a star, and comparing the mass of the star to other stars, it's possible to calculate the approximate age of a star, but probably not to within 10%. A lot of it is guesswork.
How can you guess the age of an star with a Earthbound telescope?
You can tell by which stage it is in. (white dwarf, for instance)
What instrument do the astronomers use to determine the chemical composition of a star?
They use a spectrograph to pass light through a prism to break it the light waves into its constituent colors. Then by looking at what colors are missing they can determine both the temperature and composition of the star.
Why do scientists use a spectrograph?
because they want to
What is a calutron?
An electromagnetic apparatus for separating isotopes of uranium and other elements according to their masses, using the principle of the mass spectrograph. It lost me at 'mass spectrograph'.
An istrument that breaks the light from an object into colors?
A spectrograph can do that.
What is the detector in a spectrograph in which spectral lines are recorded photographically?
The detector in a spectrograph that records spectral lines photographically is a photographic plate or film. This photographic medium captures the light from the spectral lines dispersed by the spectrograph, allowing them to be recorded for analysis and interpretation.
Instrument used by astronomers to spread light?
A spectroscope is used to diffuse the light from a star into its spectrum, so that astronomers can analyze the elements that make up the star. The same sort of instrument can be used to analyze the elemental composition of ANYTHING; for terrestrial uses, the instrument is called a spectroGRAPH.
