what is that?
>> Anonymous
probably some element's light absorption spectrum.

i herd its dna

supposedly it's a light spectrum of all the colours it's possible to see, minus one you can't see due to radiation, or at least thats what I remember reading when I first saved it.

So, why can't I see the little black bits?

If you could catch a rainbow and put it under a microscope you would see that it was not a continuous blend of colors. Along the width of it would be seen, scattered irregularly, dark patches. Atoms and molecules in the Sun’s atmosphere pick out specific frequencies of light and absorb them, diminishing their intensity by comparison. This images shows the spectrum of light from the Sun stretched out to make these absorption lines visible. We use the reverse of the idea (emission lines) when we make colored lights. For instance, we excite sodium atoms to emit a signature orange light in street lamps. In this image you can see two prominent dark bands in the yellow-orange section which are the absorption due to sodium.

8192 x 8192 196.7 Mb 24-bit color TIFF http://www.noao.edu/image_gallery/images/d5/sunsq.tiff

A high resolution version of the spectrum of our Sun, this image was created from a digital atlas observed with the Fourier Transform Spectrometer at the McMath-Pierce Solar Facility at Kitt Peak National Observatory, near Tucson, Arizona (`Solar Flux Atlas from 296 to 1300 nm' by Robert L. Kurucz, Ingemar Furenlid, James Brault, and Larry Testerman: National Solar Observatory Atlas No. 1, June 1984.). The images shown here were created to mimic an echelle spectrum, with wavelength increasing from left to right along each strip, and from bottom to top. Each of the 50 slices covers 60 angstroms, for a complete spectrum across the visual range from 4000 to 7000 angstroms. The Sun is a G2 star, and this image covers the same wavelength range in the same format as the spectrum of Procyon, type F5, and the spectrum of Arcturus, type K1 (or K2). Note: NSO/Kitt Peak FTS data used here were produced by NSF/NOAO.

anyways, lots of cool astronomy images at

if u feel like sifting through them

Doesn't answer my question from 242322. I can see sodium light, so the spectrum as given is not all the colors that it is possible to see.

it does answer it.

I don't believe that the OP is a spectrum from the Sun.

Light Beam Industries, LLC has developed a new solid state light emitting plastic. The LEC (Light Emitting Converter) material is based on patents by inventor Daniel Naum. This new substance uses fluorescent laser dyes and solid state light sources in conjunction with optical waveguides to generate multicolored or white light in a new innovative way.
Eugene, Oregon (PRWEB) June 21, 2007 -- Light Beam Industries, LLC has developed a new solid state light emitting plastic. The LEC (Light Emitting Converter) material is based on patents by inventor Daniel Naum. This new substance uses fluorescent laser dyes and solid state light sources in conjunction with optical waveguides to generate multicolored or white light in a new innovative way.
http://www.light-beam.net/plastic_light.html
The light is generated by wavelength shifting through a photoptic process of absorption and emission in the plastic material, which is a cross linked polymer. The shorter wavelengths of light from the solid state emitting source are absorbed completely, or partially if so desired, and re-emitted as light at longer wavelengths.
LEC material has a wide range of lighting potential, as well as energy saving applications such as improving solar cell efficiency. Other uses include architectural lighting, instrument panels and switches, as well as, solid state laser dye rods.
tl;dr
look at da purty colors

I read about LightEmittingPolymers (LEP) from an old magazine from the late -70.
So thats nothing new.
