The sun emits light in all wavelengths by black-body radiation. (Because it is very hot, a lot of this radiation is in the visible range, unlike objects at temperatures we're more familar with, which emit in infrared.)
Because of quantum mechanics, there are only certain orbits an electron can occupy around the nucleus of an atom. Normally, an electron orbits as close to the nucleus as possible, but if energy is added, it can go to a higher orbit. Since only certain orbits are possible, only certain amounts of energy can be absorbed or emitted when moving between orbits.
Quantum mechanics also theorizes that the energy of a photon is determined by its wavelength. So light in certain wavelengths can be, and will be, absorbed more than others before leaving the sun. When the sun's light is separated into its spectrum, dark lines appear where these wavelengths would be.
Different energies are characteristic of different elements, so the lines can indicate what elements are present in the sun.
What else can I help you with?
Is solar spectra a continuous spectra?
The Sun spectra is considered continuous.
Who discovered the dark line spectrum?
The dark line spectrum was first observed by Joseph von Fraunhofer in 1814 during his study of the Sun's spectrum. These dark lines are now known as Fraunhofer lines and are caused by absorption of specific wavelengths of light by various elements in the Sun's atmosphere.
What kind of spectrum do dark lines appear against a bright a bright background of colors ranging from red to blue?
Dark-line spectrum is a "photo-negative" of emission spectrum. It is the gaps that appear in precisely the same location as corresponding bright lines. produced by a cool gas with a hot solid and you
When was The Dark Side of the Sun created?
The Dark Side of the Sun was created on 1976-01-26.
What is the correct way to say The dark clouds will lighten as the sun lowers?
The answer is: The dark clouds will lighten as the sun lowers.
When was Line Spectra created?
Line Spectra was created in 2006.
Is solar spectra a continuous spectra?
The Sun spectra is considered continuous.
Can you use emission line spectra to determine the presence of metallic ions in our sun?
Yes, it is possible to use emission line spectra to determine the presence of metallic ions in the sun. Solids, liquids, and dense gases emit light of all wavelengths, without any gaps. We call this a continuous spectrum
How did they know that there was an undiscovered element in the sun?
Helium was discovered in the Sun by the French chemist Jules Janssen (18.08.1868) studying the spectra of Sun during an eclipse. He observed a new unknown line at 587,49 nm - this is a specific spectral line for helium.
What happens to the temperature from the surface of the sun to its center?
stuff happens Hydrogen atoms need nearly 30 kT to be torn apart This happens on the surface of the sun We can tell this from the line spectra
Who discovered the dark line spectrum?
The dark line spectrum was first observed by Joseph von Fraunhofer in 1814 during his study of the Sun's spectrum. These dark lines are now known as Fraunhofer lines and are caused by absorption of specific wavelengths of light by various elements in the Sun's atmosphere.
Stars produce different spectra mainly because?
The cavity radiation spectrum comes from surface temperature. Bright line (emission) spectra come from hot elements near the surface. Dark line (absorption) spectra come from cooler elements further out. Because they're at different temperatures and have slightly different elemental ratios, each star produces a unique "fingerprint".
What are the differences between line spectra and continuous spectra in terms of their characteristics and properties?
Line spectra are composed of distinct, discrete lines of light at specific wavelengths, while continuous spectra consist of a continuous range of wavelengths without distinct lines. Line spectra are produced by excited atoms emitting light at specific energy levels, while continuous spectra are emitted by hot, dense objects like stars. Line spectra are unique to each element and can be used to identify elements, while continuous spectra are characteristic of hot, dense objects emitting thermal radiation.
Do lines of a particular element appear at the same wavelength in both emission and absorption line spectra?
No, lines of a particular element do not appear at the same wavelength in both emission and absorption line spectra. In absorption spectra, dark lines are seen where specific wavelengths are absorbed by elements in a cooler outer layer of a star or a cooler interstellar cloud. In contrast, emission spectra display bright lines when elements emit specific wavelengths of light at higher energy levels.
How can forensic scientists use emission line spectra and absorption spectra?
Forensic scientists can use emission line spectra and absorption spectra to analyze trace evidence, such as glass fragments or paint chips, found at a crime scene. By comparing the spectra of the collected samples with reference spectra, scientists can identify the chemical composition of the evidence and link it to potential sources or suspects.
What is the eclipse about?
An eclipse is when the earth, moon and sun are all in a straight line, from earth it looks like the sun has turned dark!
How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
