Why won't the method used to discover the chemical composition of stars work for the moon and planets?
The method used to discover the chemical composition of stars, called spectroscopy, is not as effective for the Moon and planets because they do not emit light like stars do. Instead, they reflect light from the Sun, which makes it more challenging to accurately determine their chemical composition through spectroscopy.
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.
How do you know what distant stars are made of?
Scientists can determine the composition of distant stars by analyzing their spectra. The light emitted by stars contains distinct absorption or emission lines that correspond to specific elements present in the star's atmosphere. By studying these spectral lines, scientists can identify the elements present in a star and determine its chemical composition.
What tool is helpful for studying the composition of stars?
Spectral analysis is a helpful tool for studying the composition of stars. By analyzing the light emitted or absorbed by a star, scientists can determine the elements present in its atmosphere. They can then use this information to understand the star's chemical composition and physical characteristics.
Are all stars made up of the same chemical composition?
No. It varies but most are same.
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..
How do astronomers determine the chemical compositions of stars?
Astronomers determine the chemical compositions of stars by analyzing their spectra, which is the light they emit split into different wavelengths. By studying the absorption lines in a star's spectrum, astronomers can identify the elements present in the star's atmosphere. Comparing these absorption lines to known spectral lines of elements allows astronomers to determine the chemical composition of stars.

What provides info about the chemical composition of stars?
The composition is determined by spectral analysis.

The set of spectral lines that we see in star's spectrum depends on the stars?
composition and temperature. The spectral lines correspond to different elements present in the star and the wavelengths of these lines are affected by the star's temperature. By analyzing these lines, astronomers can determine the chemical composition and other characteristics of the star.
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.
How do you know what distant stars are made of?

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.
