Ultraviolet & Infrared Light...

jatslo · Apr 6, 2005

You cannot make the color violet without the colors red, and blue. Primary Colors: WHITE à Ultra YELLOW RED BLUE BLACK à Infra When will the hotshot astronomers discover the rest of the spectrum? You should solve for Vitamin E, when you figure out the light spectrum.

The "primary colours" of light are Red, Green and Blue. When you know even that much, come back and we'll discuss the rest of the electromagnetic spectrum.

The "primary colours" of light are Red, Green and Blue. When you know even that much, come back and we'll discuss the rest of the electromagnetic spectrum. Green? Green is a byproduct of yellow and blue! You want to try and defend your precious little light spectrum, then bring it on. Sounds like a bunch of science fiction to me.

*sigh*If you are using a Windows PC, start the "Paint" application. Double click on the black square in the pallete at the bottom of the window, then click "Define Custom Colors". (Note that the color is defined using Red, Green and Blue.)Enter 255 in the Red and Green boxes -- the resulting colour is yellow.QED.

When you know even that much, come back and we'll discuss the rest of the electromagnetic spectrum. Make an example out of me; I dare you. I am an artist, and I know a great deal about colors. Have you heard of a color wheel, particle unification theorems? How about a photon wave versus a particles? Hello!!! Please enlighten us ;o)

I'm afraid I don't understand your question...

jatslo · Apr 6, 2005

I'm afraid I don't understand your question... Don't be afraid. My post is not really a question. If you need a question to get started then how about the following: What is fact, what is non-fact, and are we finished discovering/identifying photons?

najab · Apr 6, 2005

>I am an artist, and I know a great deal about colors.I hope your art is better than your science. <img src="/images/icons/rolleyes.gif" />There are two 'flavours' of primary colours. Your post referrenced the subtractive primaries, where the colour percieved by the eye depends on the wavelengths which are absorbed by the paint. However, when discussing the electromagetic spectrum one has to refer to the additive primaries - where the perceived colour produced depends on the mixing of red, green and blue light.Do a Google search on these two terms: "additive primary colors" and "subtractive primary colours".

Is English a second language for you? Aspects of your post seem to indicate that it is. This might be where some of the confusion is coming from. Don't be afraid. See, I am not afraid as in "experiencing fear"; I am politely saying your post does not make sense. My post is not really a question. Part of it was...I can point the part out to you, if you wish... What is fact, what is non-fact, and are we finished discovering/identifying photons? I see you subscribe to the ancient greek school of teaching. It tends to make the speaker sound pretentious, so why don't you just clearly, logically lay out your arguement instead?

So what, I could of programmed it with yellow as the primary color, instead of green. That's just a product of someone being cute. Hydrogen Metal on the Horizon However, it appears that metal hydrogen becomes opaque under compression. But, it is a good link for understanding the pressures it appears are required. I'll scout around for updates on the research and see if there is anything out there. At 290 GPa, LeToullec and colleagues discovered that the hydrogen sample turned white, then yellow, orange and red, before becoming opaque at 320 GPa. They also established that its structure remains stable above a pressure of 160 GPa. --- http://physicsweb.org/articles/news/6/4/6/1 sample turned white, then yellow, orange and red, before becoming opaque at 320 GPaWhat is the significance of this experiment to light?

jatslo · Apr 6, 2005

Here I'll make it simple for you since you're having trouble: What is light?

najab · Apr 6, 2005

Have you done the 'research' I suggested?

centsworth_II · Apr 6, 2005

http://www.handprint.com/HP/WCL/color4.html#primary Handprint.com is an excellent website for artists and anyone else interested in color theory. It's a very extensive site. I just gave the link to the area discussing primary colors. <div class="Discussion_UserSignature"> </div>

sample turned white, then yellow, orange and red, before becoming opaque at 320 GPa What is the significance of this experiment to light? Perhaps that the photon energy absorption changes with pressure?

Saiph · Apr 6, 2005

as najab says, there are two different sets. Those for paint, and those for light. He did a very good job of stating why (additive vs subtractive). Also, I can make violet without using the other colors. I just emit an appropriately sized photon. BTW, astronomers use a lot of the spectrum: Gamma ray, x-ray, ultraviolet, visible, infrared, microwave, radio And all the subsections in each. <div class="Discussion_UserSignature"> --------------------SaiphMOD@gmail.com -------------------"This is my Timey Wimey Detector.

Here I'll make it simple for you since your have trouble: Actually, this illustrates my point about your language skills: Here I'll make it simple for you since YOU'RE HAVING trouble As for your question, you might want to be more specific, as I suspect you're disagreeing with some aspect of physics that you have not mentioned yet. If you ARE really honest in this question, then here: http://library.thinkquest.org/27356/p_index.htm

jatslo · Apr 6, 2005

Gamma ray Please expand!

najab · Apr 6, 2005

Well, you see a particle, he sees a wave - let's call the whole thing off! <img src="/images/icons/laugh.gif" />

najab · Apr 6, 2005

Gamma ray Please expand! Okay: "X-Ray". *bu-dum-ching* Gamma "rays" are nothing but extremely high frequency electromagnetic radiation.

Saiph · Apr 6, 2005

I was reffering to wavelength, but that's the same thing. I'll emite a photon of ~400 nm from an appropriate atomic transition. Can't get much purer than that, and it's pretty blue/purple. Gamma-rays. Same thing as all light (an electromagnetic wave) but the very high energy end. Often given off by radioactive decay amongst other sources. <div class="Discussion_UserSignature"> --------------------SaiphMOD@gmail.com -------------------"This is my Timey Wimey Detector.

jatslo · Apr 6, 2005

Actually, this illustrates my point about your language skills: Here I'll make it simple for you since YOU'RE HAVING trouble Whoops, I fixed that for you. I suspect you're disagreeing with some aspect of physics that you have not mentioned yet. Very good! There is more than one aspect. http://www.grandunification.com/hypertext/Balls_of_Light_3.html

gfpaladin · Apr 6, 2005

http://www.grandunification.com/hypertext/Balls_of_Light_3.html What is very interesting is that an INSPEC search on J. Nordberg turns up 185 hits from 1995 to date...not ONE having to do with this theory. Am I to conclude this has never been accepted in a refereed journal?? If true, is there a REASON why?
