an instrument that breaks the light from an object into colors and photographs the reflecting spectrum?

Optical Spectrum Analyzer (OSA) is probably what you're looking for...nice for discovering chemical composition of light source and probably a zillion other different things.

droplets of water in the air refract light and break it into the visible specturm. thats way you see the different colors.

Any three colors (or frequencies) of light which produce white light when combined with the correct intensity!\n\n"White light can also be produced by combining only three distinct frequencies of light, provided that they are widely separated on the visible light spectrum. Any three colors (or frequencies) of light which produce white light when combined with the correct intensity are called primary colors of light. There are a variety of sets of primary colors; yet,the most common set of primary colors is red (R), green (G) and blue (B). When red, green and blue light are mixed or added together with the proper intensity, white (W) light is obtained. This is often represented by the equation below:\n\nR + G + B = W\n\nIn fact, the mixing together (or addition) of these three primary colors of light with varying degrees of intensity can produce a wide range of other colors. For this reason, television sets and computer monitors produce the range of colors on the monitor by the use of of red, green and blue phosphors."

Of course, sunlight is made up of many colors.  However, we can think about "original" (or "monochromatic", or more realistically nearly monochromatic) yellow lights from other sources (like a laser).\n\nWith the composed yellow, you can separate the green and the red back out.  One way to do this would be with a prism.  While the monochromatic yellow light would just stay yellow, the composed red+green would separate back out, with each color in its position in the rainbow.\n\nA more sophisticated way to do this would be with a spectrometer.  The monochromatic yellow would show just the one wavelength, in the yellow part of the spectrum.  The composed light would show two wavelengths: one each in the green and red parts of the spectrum.  It would show no light in the yellow part of the spectrum.\n\nSnawshia is right about the speed: in a vacuum, they'll have the same speed.  In other media (water, glass, etc.), each color may have a slightly different speed.

Try this link:\n\nhttp://www.scitoys.com/scitoys/scitoys/light/cd_spectroscope/spectroscope.html\n\nThe link below shows how to make a spectroscope, too, only at first glance it seemed a whole lot more complicated.\n\nhttp://www.uwm.edu/~awschwab/specweb.htm\n\nHope it helps! Good luck! :D

By the process called spectroscopy. It is the separation of light spectrum by different methods (a prism more often). Now, a type of atom, like helium for example, will absorb a small wave light in the light spectrum (this appearing to us like a thin, black, vertical line). Every atom type absorbs different light Wave. By knowing the spectrum of every single atom, we can superpose them and "see" who's`s who, only by having sun light

If you shine a white light through a prism, the light is refracted and you get a rainbow. Thats how you can see the different wavelengths in white light.

Since you need simple and portable, how about starting with something that uses light and prisms to create the spectrum? \nFrom there, you could go to show how rainbows are created ( where the light must be, what the sequence of the rainbow spectrum is) or compare how light colors mix compared to how m=paint colors mix.  I don't know if that is appropriate for the 10 th grade.  But working with light and prisms is always fun.\nmagnetism is always fun, too.

As no one else has had a crack at this, I'll have a go with my best guess. Have you access to a reflectance spectrophotometer? Instead of shining light through a sample, it measures light reflected from a sample. At a pinch, you might be able to modify a uv/vis spectrophotometer to measure this.\n\nI hope this helps.

no i don't have any info. but i think we're able to detect all of the colors of the spectrum.

All objects that you can see absorb some light.  Black objects absorb all light while color objects absorb all but that spectrum of light.  Something white absorbs very little light.  If something absorbs no light, you will not be able to see it because no light is reflected back to your eye.

Digital imaging device, like a digital camera.

White light is not split up by different particles in the air (the exception are water droplets in a rainbow, the blue sky and the orange and red of sunsets and sunrises). Objects outside the atmosphere reflect back their colors, without white light being broken up by air. The moon is yellow, Mars is red and look at all the colors of Jupiter. \n\n\nWhite light is made up (already contains) the different colors of the visible light spectrum: Red Orange Yellow Green Blue Indigo Violet. (Roy Green bit Iris Vaughn is a mmemonic to remember the colors) \n\nWhat distinguished the different colors in the spectrum is their wavelength. When white light hits an object like grass or wood only the color you see the object as, is reflected, the other colors are absorbed.

What a dope, actually this already exists.  It’s called the Focal Light Projector; also more subclassfactions of this marvel is Particle Light Projector, and the Vaporizer Particle Projector.

Here are a couple sites I found:\nhttp://boreal.com/category.asp_Q_c_E_546587\nhttp://www.learningthings.us/acatalog/plastic_mirrors.html\nhttp://www.teachersource.com/catalog/page/Color_Light_Sound/Mirrors/?id=b459f49088b5d98c2a3d0218b9bbcc90\nLet me know if these help.

It looks black.  When something absorbs all wavelengths of light t appears black.

A spectrum is the derivative of broken light through a triangular shaped crystal, giving  as a result a spectrum or a rainbow of colors, and is used to determine many things about the light source. e.i. the composition of elements or gases of the source, among other uses. How scientists determine results is by measuring the amplitude and intensity of each color in the spectrum.
