There are a couple of things that cause specific lines to appear in a line spectrum. Two of these things are density and wavelength.

∙ 11y agoyou get line spectra when an excited atom (gained extra energy) releases this energy. The energy is gained by electrons moving from one energy level to one of a higher energy level. The atom is not happy (too much energy) so it gets rid of it. The electrons jump back to their original level releasing the energy gained as light of a fixed frequency, hence a fine line.

Density and wavelengths of absorbed or emitted protons are two things that cause specific lines to appear in a line spectrum.

What causes lines in a line spectrum?
Wavelengths of absorbed or emitted photons Every line in a line spectrum is caused by a transition, from one quantum state to another quantum state, involving electrons.
What is an atoms spectrum?
when a beam of white light is passed through the vapours or a gas, the element absorbs certain wavelengths, while the rest of wavelengths are passed through it. The spectrum of this radiation is called atomic absorption spectrum.The missing wavelengths appear as dark lines in the spectrum.
In which case will the woman see a just a spectrum that is almost entirely black except for few bright emission lines?
The spectrum that she will be observing is called an emission spectrum, in which electrons are excited to a higher energy state and then drop back down to the ground state, during which the electrons will emit photons of specific wavelengths, which will be observed as bright lines of color on what appears to be a black background.
How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
An emission spectrum depend on electrons transition in the atom of a chemical element; and elements are different.Absorption spectrum is based on the different absorption pics of different molecules, depending on the frequency of radiation.Spectral methods are largely used in analytical chemistry.
Why can the bright-line spectrum of an element be used to identify an element?
The wave lengths of lines of the spectrum are different for each chemical element.
What are the Dark lines that appear in a spectrum of light from a star called?
absorption lines! :)
Can you describe an astronomical spectrum?
'Astronomical spectrum' is not a specific term. I suspect you are thinking of the emission spectrum of a star, which can tell us a great deal about the composition of the star. Light and other radiations from the object are spread out into constituent wavelengths and dark lines appear across the spectrum at certain specific wavelengths which are characteristic of elements present.
How does the color of the flame correspond to the distinct lines in its spectrum?
The color in the flame is the representation of a specific line in the spectrum.
What causes the lines in an atomice spectrum?
wavelengths of absorbed or emitted photons
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
Why do black lines appear on a star's absorption spectrum?
The lines indicate which atoms are in the outer layers of stars. The location of the lines is always the same when they form.
What causes spectra lines?
Absorption of energy at atom energy levels cause the line spectrum.
What is the relationship of the colors you saw and the lines of the electromagnetic spectrum produced by metals?
Each chemical element has a different spectrum; and each color has a specific wavelength.
What is the relationship between the colors you saw and the lines of the electromagnetic spectrum produced by the metals?
Each chemical element has a different spectrum; and each color has a specific wavelength.
Star radiate different colors and lines based on their composition this is know as its?
It sounds like you're describing an emission spectrum. An emission spectrum will contain bright lines at specific colors, each of which is characteristic of a particular chemical element.
What were dark lines in the spectrum named for?
Dark lines especially in solar spectrum have been named as Fraunhofer lines. These line are good examples for line absorption spectrum
How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
