What does the presence of dark lines in the solar spectrum mean?
The dark lines represents the absorption of energy at that frequency, E=hf.
How is a star simmular to the Sun if it has the same absorption lines in its spectrum that occur in the Sun's spectrum?
because they will have the same elements in the atmosphere...
How much do astronomers use spectral analysis to classify stars?
Astronomers use the patterns of lines observed in stellar spectra to sort stars into a spectral class. Because a star’s temperature determines which absorption lines are present in its spectrum, these spectral classes are a measure of its surface temperature. There are seven standard spectral classes.
What are the similarities between emission and absorption spectra?
The lines are at the same frequencies
Is indium name after India?
No, it is named from the blue (indigo) lines in its spectrum.
How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
The number of lines in the emission spectrum is the same as in the absorption spectrum for a given element. The difference lies in the intensity of these lines; in emission, they represent light being emitted, while in absorption, they represent light being absorbed.
In what ways is the pattern of lines in a stars absorption spectrum unique?
because all of the different lines of a star's elements appear together i its spectrum, making the pattern different everytime
Dark lines in an absorption spectrum are called?
Dark lines in an absorption spectrum are called absorption lines. These lines correspond to wavelengths of light that have been absorbed by specific elements or molecules in the sample being analyzed. They appear as dips or gaps in the spectrum where less light is detected.
Is an absorption spectrum also called a bright line spectrum?
No, an absorption spectrum and a bright line spectrum are not the same. An absorption spectrum is produced when light is absorbed by atoms or molecules, showing dark lines at specific wavelengths. On the other hand, a bright line spectrum is produced when atoms or molecules emit light at specific wavelengths, creating bright lines in the spectrum.
What part of the star is responsible for the dark lines in its spectrum?
The dark lines in a star's spectrum are caused by absorption of specific wavelengths of light by the elements in the star's outer atmosphere. This absorption occurs when the elements in the atmosphere absorb photons of specific energies, leading to the creation of dark absorption lines in the spectrum.
What are some comparisons with a absorption spectrum and a continuous spectrum?
An absorption spectrum shows dark lines at specific wavelengths where light has been absorbed by a substance. A continuous spectrum shows all colors/wavelengths with no gaps, like the rainbow. The main difference is that the absorption spectrum has specific dark lines while the continuous spectrum is smooth and uninterrupted.
What are the Dark lines that appear in a spectrum of light from a star called?
The dark lines that appear in a spectrum of light from a star are called absorption lines. These lines are caused by the absorption of specific wavelengths of light by elements in the outer atmosphere of the star. Absorption lines help astronomers identify the chemical composition of stars and other celestial objects.
Why would the absorption spectrum of each element have lines in the same places as in its emission spectrum?
The absorption spectrum of an element have lines in the same places as in its emission spectrum because each line in the emission spectrum corresponds to a specific transition of electrons between energy levels. When light is absorbed by the element, electrons move from lower energy levels to higher ones, creating the same lines in the absorption spectrum as the emission spectrum. The frequencies of light absorbed and emitted are the same for a specific element, resulting in matching lines.
What is a dark line found in a spectrum is called?
A dark line found in a spectrum is called an absorption line. Absorption lines are created when atoms or molecules absorb specific wavelengths of light, resulting in dark lines in the spectrum where that light is missing.
What are dark lines in a stellar spectrum called?
The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star. ================================ Fraunhofer's spectral lines.
What is a band spectrum?
A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.
