How does a spectrograph provide information about stars chemical composition?
A spectrograph is an instrument for chemical analysis.
Are all stars made up of the same chemical composition?
No. It varies but most are same.
Can Scientists learn about the chemical composition of stars by analyzing the light they transmit.?
Scientists can learn the composition of a star from the amount and types of electromagnetic radiation, including light, that it gives off. Additionally, scientists can determine the rate of nuclear fusion from the amount of light released per unit of time.
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.
Why won't the method used to discover the chemical composition of stars work for the moon and planets?
Moons and planets emit none or very little of the rays needed to detect chemical compositions.
What is stellar spectroscopy used for?
The purpose of stellar spectroscopy is to determine the chemical composition of stars, the temperature and some other characteristcs..
What provides info about the chemical composition of stars?
The composition is determined by spectral analysis.
What characteristics do scientists measure to determine the temperature and composition of stars?
the light radiated from the stars
How do astronomers determine the chemical compositions of stars?
The answer is long and complicated, and it is too long to place here. You need to read an entire encyclopedia articles on spectroscopy and the chemical composition of intersteller objects. D.A.W.
How does a spectrograph provide information about stars chemical composition?
A spectrograph is an instrument for chemical analysis.
What is the chemical composition off most stars?
Stars contain hydrogen, helium and a little iron.
Spectrum indicates what in the stars atmosphere?
The chemical composition of the star atmosphere.
How do scientists determine a stars composition?
Light wavelength and light spectrum i believe.
Scientists determine the composition and temperature of stars?
To determine the chemical composition of stars, scientists look at what's called the emission spectrum of the stars, which can be obtained from the light coming from the stars. Thin lines are observed in different parts of the spectrum, which correspond to different chemicals. In other words, the lines are like fingerprints of chemicals. By looking at these fingerprints, one can determine what type of chemicals are present in the star. To determine the surface temperature of stars, we use the Wien's Law. It states that: Peak wavelength x Surface Temperature = 2.898x10-3 Peak wavelength can be determined by looking at the light coming from the star in question. It is the wavelength with the highest intensity.
The set of spectral lines that we see in star's spectrum depends on the stars?
Chemical composition ;-)
What makes a star's spectrum appear to be different from another stars?
The chemical composition of the star.
What is an astrochemist?
An astrochemist is an expert in astrochemistry, the study of the chemical composition of stars and outer space.
