Elements are identified based on their absorption spectra. Every element absorbs a unique set of frequencies when light passes through it. Scientists can determine which elements are present based on which portions of the star's light are absorbed.

Studying Fraunhofer lines helps to identify what on the stars?

Studying Fraunhofer lines helps identify the chemical composition of stars. These lines represent specific wavelengths of light that are absorbed by elements in a star's atmosphere. By analyzing the pattern of these lines, astronomers can determine which elements are present in the star.


Why do astronomers use frequency?

Frequency or wavelength is used in the spectrum of astronomical objects in order to identify which chemical elements are present in 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.


What is similar between chemists and astronomers?

Chemists deal with the table of elements and the universe contains these elements. Astronomers study space and the planets stars and whatever else is in space contains these elements. Chemistry helped the U.S. to be the first to the moon.


How do astronomers know that hydrogen is present in almost every star in the universe?

Astronomers use spectroscopy to analyze the light emitted by stars. By studying the absorption lines in a star's spectrum, astronomers can identify the elements present in its composition. Since hydrogen leaves a distinct signature in these absorption lines, scientists have found that hydrogen is the most abundant element in stars, including our Sun.

What do astronomers consider heavy elements?

Astronomers consider elements beyond hydrogen and helium, such as carbon, oxygen, nitrogen, and iron, as heavy elements. These elements are created through processes like nuclear fusion in stars and supernova explosions.


How do astronomers identify constellations?

Constellations are simply pattern of stars that with a little imagination, resemble objects, people or animals. You don't need anything to identify them other then your eyes and a little imagination.


Are scientists able to identify elements in stars by studying their spectral lines?

Yes, they are.
