Dark lines especially in solar spectrum have been named as Fraunhofer lines. These line are good examples for line absorption spectrum

Is it true that The dark lines of the spectrum were named for Kirchhoff?
No. You're thinking of Fraunhofer. A natural slip for English speakers.
What is s band spectrum?
Band spectrum is the spectrum given by the molecules. It consists of series of closely spaced lines known as bands separated by the dark spaces.
Why in an absorption spectrum the back ground is bright and the lines are dark?
Because it is an absorption spectrum. An absorption spectrum begins with a source of pure white light. This hits a prism which spreads it out into a spectrum and the result shows on a screen as a bright band of colours. If you put this into a glass case and seal it to the outside world, nothing changes. Now if blow a gas into the tank, the atoms in the gas absorb different wavelengths (colours) of light. The result you see is a normal spectrum of colours, but with one or more dark lines across it. This is because the atoms in the gas through which the white light is shining are absorbing some or all of various colours in the spectrum. What those colours are is absolutely characteristic and definitive of that particular gas. This is a very powerful technique for identifying elements which are present only in trace amounts. An interesting light on this is that the element Helium was first discovered not on earth, but on the sun by some dark lines in the sun's spectrum which did not belong to any known element.
Is an atomic emission spectrum a continuous range of colors?
No. Atomic emission spectrum is non-contiuous and it is named as line spectrum.
What is a linear emission spectrum?
A linear emission spectrum is the collection of frequencies that a substance can emit when the atoms in it are excited (say, by heating) or can absorb. Where visible light frequencies are involved the emitted frequencies may be made to appear as a series of coloured lines on an axis representing frequency. Such a spectrum may also be represented as a series of dark lines presented against a straightened rainbow of colours where the axis along the edge of the rainbow represents light frequency. Please see the link.
What part of the star is responsible for the dark lines in its spectrum?
Atoms in the atmosphere of the star is responsible for the dark lines in its spectrum.
Continuous spectrum with dark lines where light is absorbed?
dark-line spectrum...
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.
Is it true that The dark lines of the spectrum were named for Kirchhoff?
No. You're thinking of Fraunhofer. A natural slip for English speakers.
Dark lines in an absorption spectrum are called?
Absorption lines
What are the Dark lines that appear in a spectrum of light from a star called?
absorption lines! :)
What does the presence of dark lines in the solar spectrum mean?
The dark lines represents the absorption of energy at that frequency, E=hf.
Why can elements in a star be separated?
Because the spectrum of the star's light can be seen to have dark lines all the way through, and each element has its own set of dark lines in the star's spectrum.
What does a star's dark-line spectrum reveal?
The dark lines reveal the atoms that are associated with the stars atmosphere. The dark lines are atom energy absorption signatures.
What does a stars dark line spectrum reveal?
The dark lines reveal the atoms that are associated with the stars atmosphere. The dark lines are atom energy absorption signatures.
Is indium name after India?
No, it is named from the blue (indigo) lines in its spectrum.
What is s band spectrum?
Band spectrum is the spectrum given by the molecules. It consists of series of closely spaced lines known as bands separated by the dark spaces.
