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.

If the woman is observing a black body spectrum that is very cold, such as an object in space with a low temperature, she will see a spectrum that is almost entirely black with only a few bright emission lines. This is because at low temperatures, the majority of the radiation emitted is in the form of discrete emission lines rather than a continuous spectrum.

Image of emission or absorption spectrum of manganese?
This would consist of several series of lines corresponding to the energies of electron transitions. They are bright lines for an emission spectrum and dark for absorbtion.
How can you Distinguish absorption spectrum from emission spectrum?
An absorption spectrum shows the wavelengths of light absorbed by a substance, appearing as dark lines on a bright background. An emission spectrum shows the wavelengths of light emitted by a substance, appearing as bright lines on a dark background. In other words, absorption involves light being absorbed by the substance, while emission involves light being emitted by the substance.
What spectrum is produced by a hot gas under low pressure and appears in a series of bright lines?
An emission spectrum is produced by a hot gas under low pressure, which appears as a series of bright lines. Each bright line corresponds to a specific wavelength of light emitted when electrons transition from higher to lower energy levels within the atoms of the gas.
What does the term bright line spectrum mean?
A bright line spectrum refers to the pattern of distinct and bright lines of different colors that are produced when an element is excited and emits light. Each element has a unique bright line spectrum that can be used to identify the element through spectroscopy.
What colour is produced when sodium is heated?
When sodium is heated, it produces a bright yellow color due to the excitation of electrons in the sodium atoms. This yellow color is characteristic of the emission spectrum of sodium.

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.
What spectrum is produced by a hot gas under low pressure and appears in a series of bright lines?
An emission spectrum is produced by a hot gas under low pressure, which appears as a series of bright lines. Each bright line corresponds to a specific wavelength of light emitted when electrons transition from higher to lower energy levels within the atoms of the gas.
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
What does the term bright line spectrum mean?

What is the difference between absorption and emission spectrum?
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
What do the bright lines in a bright light spectrum tell us?
The bright lines in a bright light spectrum, known as emission lines, indicate the specific wavelengths of light emitted by excited atoms or molecules when they return to a lower energy state. Each element produces a unique pattern of emission lines, allowing scientists to identify the elements present in a light source.
The lines in the bright line spectrum of an atom are due to what?
The atomic line spectrum comes from the emission of atoms of different elements that are in an excited state. Each element has its own unique atomic emission spectrum.
An astronomer finds that the visible spectrum of a mysterious object shows bright emission lines What can the astronomer conclude about the source?
it comes from a hot, tenuous gas
Which type of spectrum can be produced by a solid liquid or gas?
An emission spectrum can be produced by a solid, liquid, or gas. This type of spectrum consists of bright lines or bands of specific wavelengths emitted when electrons in the material transition to lower energy levels.
How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
An emission spectrum of a gas in a discharge tube shows only specific wavelengths of light emitted when electrons in the gas atoms transition to lower energy levels. This produces distinct colored lines on a dark background. In contrast, a white light spectrum shows a continuous range of wavelengths across all colors of visible light due to the presence of a broad spectrum of colors.
