I work with a bunch of nerds, like myself. A question was posed this morning about spectrographs. Can a spectrograph see color? I think that it should be technically possible, but I am not 100% sure. Are there any scientists out there that can lead me in the right direction? I have a background that includes some radio and spectrum theory so I understand how the radio spectrum works basically, which is why I believe that a spectrograph should be able to pick up color waves, but some in my office, with the same background, disagree...any help here?

Define color. Does color even exist? Who says a wavelength of 900nm has to equal red (or whatever)? :)
By using the word "see" you're anthropomorphizing the spectrograph. The way they work is simple, really. Check out this link:
How does a spectrograph work?
Remember, the radio spectrum includes light waves. Why should there be any difference?

Point taken. I change my question to:
Can a spectrograph detect color? Color being the wavelengths between Red and Violet, or whatever is the generally accepted name of the highest wavelength visible to the human eye.
Thanks for the link, I'll check it out in a few.

colour does not exist. It has the same basis in reality as horny and anrgy: that is, human responses to certain stimulii in their bodies. Can an electron be horny? (I hope not, or quantum physics will get a lot more difficult. In order to calculate a cross section (interaction probability) you'd have to factor in if the particles were horny, upset, or gay. If any particles are gay it's definately the J/ψ. )
You can always turn tricks for a few extra bucks. If looks are an issue, there's the glory hole option, but don't expect more than ... tips.

Oh come on!
You physicists have been calling particles "horny", "upset", and "gay" for years!
Healthy genes act as team-players. They are teamish!
Their winning plays are salvations of an aliveness of which they are a part.
Only a fraction of genes are selfish/parasitic (and they parasitize teams).

No! Strange perhaps, but not gay. It's about time all these gay particles came out of the closet though. The fabutron, the campion and, of course, the gaytrino.

I dunno... "Charmed" is pretty close to Gay.
I hear the fabutron can produce all three flavors of gaytrinos.
Bighead, for the definitive work on understanding light and diffraction, pick up Feynman's "QED - Quantum ElectroDynamics" .

Yes, that is an awesome book!

yeah, charmed is a bit gay now that you mention it. Don't forget though that the gay-psiparticle is full of charm

Thank you for the enlightenment Choobus, very interesting. I also read that the J/ψ subatomic particle is called sometimes "the gypsy"

But it's flavor-neutral. Doesn't that make it bi?

It's about how robots can sense colours. Doubtless he was trying to use it as some sort of counter-argument to colours only being a subjective notion. Quite how it would be anything of the sort is beyond me.
