How do scientist determine the composition of a star?
Scientists determine the composition of a star by studying its spectrum, which is produced by analyzing the light emitted by the star. By examining the absorption lines in the spectrum, scientists can identify the elements present in the star's atmosphere and infer its overall composition. Additionally, measurements of the star's temperature, luminosity, and mass can also provide valuable information about its composition.
What spectrum is used to determine the composition of a planets atmosphere?
The spectrum used to determine the composition of a planet's atmosphere is primarily the electromagnetic spectrum, specifically the infrared and visible light regions. Scientists analyze the absorption and emission lines within this spectrum to identify the presence of specific gases, as different molecules absorb light at characteristic wavelengths. This technique, known as spectroscopy, allows researchers to deduce the atmospheric composition, temperature, and even potential habitability of the planet.
The optical spectrum of the light from the sun could be used to identify what kind of atoms are present in or near the sun?
Yes, the optical spectrum of sunlight contains absorption or emission lines that can be used to identify the elements present in the sun. Each element produces a unique pattern of lines in the spectrum, allowing astronomers to determine the composition of the sun and other celestial bodies.
When a star's spectrum shows dark lines against a continuous background what does this indicate?
Dark lines in a star's spectrum indicate absorption lines, which are caused by elements in the star's atmosphere absorbing specific wavelengths of light. These lines provide information about the composition and temperature of the star.
What type of spectrum is produced when light emitted from a hot low-density cloud of gas passes through a prism?
When light emitted from a hot low-density cloud of gas passes through a prism, it produces an emission spectrum. This spectrum consists of bright lines at specific wavelengths, corresponding to the unique energy transitions of the atoms in the gas. Each element emits light at characteristic frequencies, resulting in distinct lines that can be used to identify the chemical composition of the gas. This is different from a continuous spectrum, which would show a smooth range of colors.
What can a scientist learn about from a stars spectrum?
scientists can tell the stars composition and temperature from its spectrum. Hope tht helps :]

What is meant by a continuous spectrum?
You can use spectra to estimate the temperature of the star: astronomical thermometer
Analysis of the of a star reveals the composition of the star?
That's done by analyzing the star's spectrum.
Explain the difference between the continuous spectrum of white light and the atomic emission spectrum of an element?
The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.
What is the significance of the fact that all macroscopic objects emit a continuous spectrum?
The significance of the fact that all macroscopic objects emit a continuous spectrum is that it provides important information about the temperature and composition of the object. This emission of continuous spectrum helps scientists understand the thermal properties and chemical makeup of the object, which can be useful in various fields such as astronomy, materials science, and environmental monitoring.
When light having a continuous spectrum passes through a cool gas what kind of spectrum is produced?
When light with a continuous spectrum passes through a cool gas, it produces an absorption spectrum. In this process, specific wavelengths of light are absorbed by the gas atoms, which correspond to the energy levels of the electrons. As a result, the continuous spectrum shows dark lines, known as absorption lines, at the wavelengths where the gas has absorbed light. This phenomenon provides valuable information about the composition and properties of the gas.
What happens to the light that is missing in an absorption spectrum?
The missing light in an absorption spectrum is absorbed by the substances in the sample and is converted into other forms of energy such as heat or chemical reactions. This absorption of specific wavelengths of light allows scientists to identify and study the composition of substances based on the pattern of light absorbed.
What kind of spectrum is used to determine the composition of a planet's atmosphere?
An absorption spectrum is typically used to determine the composition of a planet's atmosphere. This type of spectrum shows specific wavelengths of light that are absorbed by different gases in the atmosphere, allowing scientists to identify the presence of specific elements or compounds.
What are the two types of spectrum?
The two types of spectrum are continuous spectrum, which shows a continuous range of colors with no gaps, and line spectrum, which consists of distinct lines of color separated by gaps.
The spectrum produced by glowing high-density gas is an a bright line emission b dark line absorption c chemical composition d temperature c continuous?
a Edit: The question is very mixed up, but I think I get the idea. It's obviously an emission spectrum. Because it is a high density gas the spectrum should be CONTINUOUS.
Is the continuous spectrum really continuous Or just too close to distinguish?
The spectrum produced by something that's heated, like the sun or an incandescent light, is continuous.
