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.
A correct use of a star's emission spectrum would involve analyzing the patterns of spectral lines produced by elements within the star's atmosphere. By comparing these lines to known atomic transitions, scientists can determine the chemical composition and physical properties of the star, such as temperature and density. This information helps astronomers classify stars based on their spectral type and understand their evolutionary stage.
Stars of spectral class M have cooler temperatures compared to stars of other spectral classes, causing their hydrogen lines to weaken and be less prominent in their spectra. The lower temperature results in lower energy levels, making it more difficult for hydrogen atoms to transition between energy levels and emit or absorb light in the hydrogen spectral lines.
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.
No. K spectral type stars (which are orange) temperature is ranging from 5,000-3,500. A spectral type stars (which are blue-white) temperature is ranging from 7,500-11,000.
Scientists studied the light emitted by stars and found that the spectral lines corresponded to those of hydrogen. By analyzing these spectral lines through spectroscopy, scientists were able to identify the elements present in stars, with hydrogen being the most abundant element. This discovery revolutionized our understanding of the composition of stars and the universe as a whole.
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.
Scientists measure the brightness, color, and spectral lines of stars to determine their temperature and composition. By analyzing the light emitted by stars, scientists can infer important information about their properties. The temperature of a star is usually determined by examining the peak wavelength of its emitted light, while the spectral lines reveal the elements present in the star's atmosphere.
they provide key information about the composition, temperature, and motion of astronomical objects. By analyzing the unique patterns of spectral lines emitted or absorbed by celestial bodies, astronomers can determine their chemical makeup, distinguish between different types of stars, and even measure their radial velocities. This allows scientists to study the properties and evolution of galaxies, stars, and other celestial objects in great detail.

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.
