I know it has something to do with the light spectrum and that it is a certain light wave, but I don't have all of the details

it is not a stupid question. mankind has woried over it for centuries. it is because blue is scattered the most and so u see it more. the scattering mechanism is called rayleigh scattering and it increases at lower wavelengths. the scattering is because of dust particles in the atmosphere.

OK, this question doesn't make sense, for two reasons:\n\n1.) Colors, by definition, are at different wavelengths. If the beam has 2 color components, each component would have it's own wavelength.\n\n2.) Your question at the end isn't a proper sentence, and is leaving a necessary part out.

I can't really answer that without more details...sorry!

it might be from the sun

The visible light region is from 0.7 µm to 0.4µm of the spectrum. The color of an object that we see is the color or wavelength of light reflected from the visible spectrum. All other colors or wavelength are absorbed. the following chemicals are different in terms of wavelength because of their different nature's regarding reflection of particular wavelength or the absorption of other.

It's been a long time but I believe it relates to the mathematical ratios between the wavelengths of the pitches of various notes... That's more physics than geometry, though.

Light 'dimming' is due to a decrease in the intensity of the light that reaches your eyes. This is different from the waves loosing energy or becoming 'shorter.'\n\nThink of it this way... When you shoot a shotgun, the pellets are very dense, grouped closely together, when the exit the barrel. As they get farther away from the barrel, they get farther away from each other. This is kind of what happens with a decrease in intensity.\n\nHere's another way, one that is more applicable to your question. Think of the surface of a star. It is, roughly, a sphere. To make this simpler, lets just think of the star as a circle. (It may help to draw this out as I'm explaining it) Let's assume that all of the light that is emitted comes straight out of the surface. A way to picture this is to draw straight lines from the center of the circle outwards. Do this for a few lines that start out very close together and are almost going in the same direction. Extend these lines out very far from the center. Do you see how, as they get farther from the center, they get farther away from each other?\n\nYou can also draw a tiny dot some distance away from the circle. This can represent the earth. How many lines that initially start out close together actually intersect this dot? Now can you see why the light gets dimmer? It is because only a small fraction of the light that is sent in our direction actually reaches us.\n\nWhile it is true that light waves do extend forever, they do not exist everywhere. To describe where something is located, you can only talk about how probable it is to be located somewhere. This is a consequence of the Uncertainty Principle.\n\nIf you want to know more, I suggest looking at wikipedia or googling Schroedinger's Equation. There are probably other people who can explain it far better than I could.

I do not know what this means.

it ain't pretty but here goes nothing.\n\n\n\nsunlight is all hues\nN and O scatter the light\nblue is spread the most\n\n\n\n\nThe first thing to recognize is that the sun is an extremely bright source of light -- much brighter than the moon. The second thing to recognize is that the atoms of nitrogen and oxygen in the atmosphere have an effect on the sunlight that passes through them. \n\nThere is a physical phenomenon called Rayleigh scattering that causes light to scatter when it passes through particles that have a diameter one-tenth that of the wavelength (color) of the light. Sunlight is made up of all different colors of light, but because of the elements in the atmosphere the color blue is scattered much more efficiently than the other colors. \n\nSo when you look at the sky on a clear day, you can see the sun as a bright disk. The blueness you see everywhere else is all of the atoms in the atmosphere scattering blue light toward you. (Because red light, yellow light, green light and the other colors aren't scattered nearly as well, you see the sky as blue.)

not exactly...they detect unusual higher-spectrum dynamic variables(like ultraviolet rays)using the same old colors we see to detect "Visible Light".

I know that different colors are "visible" at different wavelengths.  So, depending on an increase/decrease in energy, you would be at varying wavelengths?

All elements when heated give off a signature in the light spectrum. For example if you heated a piece of pure iron until it glowed then put a prism in front  of the light, you would see the spectrum of light -- obvious stuff. However because it is the metal iron there would be slots-- frequencies that would be missing. These signatures are all very different from each other depending on which element(s) are giving off light. When something is red shifted the signature is still there but it's place in the spectrum is in the wrong place. It has shifted to the red end of the spectrum-- it is in the longer or red end of it.\n\nThere is two ways to think of this, the other is that when heated elements will give off light in only so many frequencies- the rest of the frequencies are missing.

the wavelength is half...\n\nvavelength and frequency are inversely proportional

First realize that since the beam is passing through something, reflection has nothing to do with it.  The only possible answer is the one that mentions refraction.

People say they are spirits. Or energy of them. But you have to be careful cause sometimes they get mixed up with dust. There is a difference. take a picture of some dust and compared the two. Also sometimes it can be the lighting in the photograph.

I think you may be referring to an oscilloscope.

I'm not really sure what you're asking for, but I'd answer this question using Physics concepts.\n\nOK, we all know that the visible light spectrum lies between the wavelength of 700nm-400nm. (That's 700 nanometer-400nanometer). 700nm is the red part of the spectrum, and 400nm is the violet part of the spectrum.\n\nAccording to your colour spectrum (ROYGBIV), orange light has a larger wavelength than yellow light.
