As mentioned above, a scanner can be used for putting a picture or text onto your computer. If you haven't seen one, they mostly look like very small copy machines(with the glass window where the object is placed). I doubt you are referring to the radio scanner, but they are devices that scan through a set of frequencies you enter, so that you can hear the police ar other emergency workers talking over their radios.

is it for website graphics ?\n \nYou can try Adobe photoshop and also check google books

The following link is about the single perspective camera. \n\nDid not really understand your comments about the question. \nI was thinking aboutGeometry was a function in a application called 3D VISION. So I just answered the question and ignored the comments.

I'm not sure of any websites.\n\nGeometry may be used in calculating out areas and doing design work.\nGeometry may be used in spacial arrangements.\n\nConsider a builder building a big complex.  At different times of the year will the shadow cast from the complex interfere with somebody else's light.  Geometry can be used to identify the answers.

I always remember it like this: it shows the text between the tags PREcisely the way it's entered.\n\nAnd it used to be used to show the code of computer programs.  In most programming languages, indentation of certain lines reveals the structure of the program (in some languages, indentation is mandatory).  To get it right without the PRE tag required a lot of toying with spaces (read: non-breaking spaces!) to get it more or less right.\n\nInside PRE tags it's a lot easier: all spaces are shown, and all characters have the same width (non-proportional characters).  Exactly what you'd want when formating computer code.

Use Spector Pro.  You can see EVERYTHING they do.

as far as i know its used for DNA figerprinting in electophoresis (i didnt spell that right).  basically you use a gel like substance, put DNA fragments in it (mixed w. dye) and put this in a solution and hook the one end of the whole device to a negative battery side or something and the other end to a positive side and the DNA fragments will seperate and u can use it to match up DNA samples w. people etc.

I believe that you are referring to a stereo-microscope. Generally stereo-microscopes have low magnification and are used for the study of macroscopic 3-dimensional objects like insects. Hope this helps.

Currently I believe that it is used in many applications- one I use frequently is chemistry panels (bloodwork)

Mostly used in science, you familiar with it displaying the rainbow with white light, it can also be used to indentify other colors of light a gases.  When using it to identify gases, you will see the rainbow, but with a line of color missing called the "absorption lines" scientists have developed a chart to referece this.  For example, Cholorine will show all the colors but a line a blue/purple will be misssing, they can reference their documents and know what gas it is.  Here is a picture I found about it,\n\nhttp://en.wikipedia.org/wiki/Image:Cumulative-absorption-spectrum-hubble-telescope.jpg\n\nMany people suppose that the main optical action of a prism is to disperse white light into its component parts, because that's what Isaac Newton used prisms for. But because dispersion is really a very small effect, it isn't the main optical action of a prism; more correctly, it should be looked at a a minor side effect. \n\nThe main effect of a prism is to deviate a beam of light. But, because of the dispersion in the refractivity of transparent materials, the deviation is slightly different for light of different colors. This slight difference in the deviation — only one or two percent, typically — is where the dispersive power of a prism comes from. \n\nIn optics, prisms made for the purpose of dispersing light are usually made with bases that are equilateral triangles, so that the angles between adjacent sides of the prism are 60°. However, prisms are also often used to re-direct light by using internal reflection; these often have bases that are isosceles right triangles, with angles of 45°-90°-45°. As optical technology developed, opticians found uses for more complicated pieces of glass with plane entrance, exit, and reflecting or refracting faces; but these are often not “prisms” in the geometric sense, but more complicated polyhedra, or even more complex shapes, with unused corners cut or rounded off to reduce weight.

Graphs r used to analyse the behaviour of some machine by examining some physical parameters. In business thay r used to anlyse and study the companies performance i.ie., their past & present records and their by making strategies and plans foe future operations.

Astronomers use parallax to measure the distance to a star. They also use this method to measure the distance galaxies. For more information see link below.

I think what you mean is FACS (Four Colour Cell Analyser) Calibur?\n\nIt uses flourescence as its detection method I think. Used in flow cytometry experiments. This website will probably explain it better than I could...\n\nhttp://www.pathology.wustl.edu/html/facilitiesfacsfaq.html

It's just a means of easily displaying the relfections of the ultrasonic system so the operator can see the echoes in a relatively easy to understand way. The operator will be able to make a better judgement of where the edges of the steel are from the scope trace than an electronic meter could which could get confused by different traces/echoes.

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.
