What causes the creation of Fraunhofer lines in the Sun's electromagnetic spectrum?
Fraunhofer lines in the Sun's electromagnetic spectrum are caused by the absorption of specific wavelengths of light by elements in the Sun's atmosphere. These elements absorb light at certain frequencies, creating dark lines in the spectrum that help scientists identify the composition of the Sun.
What are the characteristics of the nitrogen spectrum?
The nitrogen spectrum consists of lines that are mainly in the ultraviolet region of the electromagnetic spectrum. These lines are produced when nitrogen atoms are excited and emit light. The spectrum is characterized by distinct lines at specific wavelengths, which can be used to identify nitrogen in various substances.
What were dark lines in the spectrum named for?
Dark lines in the spectrum were named after German physicist Joseph von Fraunhofer, who first systematically studied them. They are commonly known as Fraunhofer lines and are formed when certain chemical elements absorb specific wavelengths of light, creating dark bands 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 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 causes spectra lines?
Absorption of energy at atom energy levels cause the line spectrum.
What causes the creation of Fraunhofer lines in the Sun's electromagnetic spectrum?
Fraunhofer lines in the Sun's electromagnetic spectrum are caused by the absorption of specific wavelengths of light by elements in the Sun's atmosphere. These elements absorb light at certain frequencies, creating dark lines in the spectrum that help scientists identify the composition of the Sun.
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 are the characteristics of the nitrogen spectrum?
The nitrogen spectrum consists of lines that are mainly in the ultraviolet region of the electromagnetic spectrum. These lines are produced when nitrogen atoms are excited and emit light. The spectrum is characterized by distinct lines at specific wavelengths, which can be used to identify nitrogen in various substances.

Dark lines in the spectrum were named after German physicist Joseph von Fraunhofer, who first systematically studied them. They are commonly known as Fraunhofer lines and are formed when certain chemical elements absorb specific wavelengths of light, creating dark bands in the spectrum.
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.
Does the helium spectrum have twice as many lines as the hydrogen spectrum?
No. In vacuum(i.e.no continuum lowering), both have an infinite number of lines in the spectrum, hence the question makes no sense.
Continuous spectrum with dark lines where light is absorbed?
dark-line 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.
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.
The composition of a star can be identified by?
the lines in its 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.
