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
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.
Which end of the visible electromagnetic spectrum has longer wavelength Red or Blude?
Deep dark red is the visible light with the longest wavelength. Violet is the visible light with the shortest wavelength.
What is a invisble light spectrum?
Most of the electromagnetic spectrum is not visible.
What will be the resulting spectrum if use a monochromatic light instead of sodium vapour lamp in diffraction grating?
You will observe a series of bright and dark fringes uniformly spaced, of the color of the monochromatic light used.
Continuous spectrum with dark lines where light is absorbed?
dark-line spectrum...
What are the Dark lines that appear in a spectrum of light from a star called?
absorption lines! :)
If dark is the absence of light what would the absence of dark be if light wasn't present?
Hi there, That is a question which is deeper than it may first appear. Mmm. I would go with dark being the absence of light, since light is actually something (electromagnetic waves). ANSWER: Light as we see it has all the spectrum colors that we can detect or frequency in essence. dark or black is the lack of these frequency or below our detection by our eyes
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 causes the dark bands observed in a solar spectrum?
The dark bands are caused from the differnet chemical elements which absorb light at specific wavelengths.
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.
When you do your eyeshadow is it supposed to go from the brow bone down light to dark or dark to light?
light to dark
What is the relationship between electromagnetic spectrum light and sight?
Anything that can reflect light is only visible to an eye... others which cannot are dark..
What type of spectrum does an incandescent light produce?
There are no bright lines and no dark lines in the spectrum, incandescent light has a continuous spectrum with all visible colors present
Who discovered the dark line spectrum?
Lippershey first discovered a dark-line spectrum.
What are the types of lighting?
It is the spectrum of light. There is infrared, ultraviolet(UV), cosmic and gamma rays, heat, and radio waves. Hope that answered your question.
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.
