What does the term bright line spectrum mean?
There are several kinds of spectra. Bright line spectrum, or emission spectrum, is when light emitted by a gas has an electrical discharge going through it, and it produces a spectrum of just a few isolated parallel lines.
The bright-line spectrum produced by the excited atoms of an element contains wavelengths that are?
in the visible light range
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.
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.
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.

Is an absorption spectrum also called a bright line spectrum?
No, its an absorption spectrum
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 do the bright lines in a bright light spectrum tell us?
to identify elements
The fingerprint of an atom is seen in its?
bright line spectrum

How did indium get its name?
its named after the bright indigo line in its spectrum
Why does the star betelegeuse appears bright in the night?
Because it is bright but not bright enough to be seen in the day.
Lightning is a bright flash of electricity produced by?
Lightning is known as a bright flash of electricity produced by a thunderstorm.
