Optics .?
Q. What are some interesting optic phenomena? eg. mirage, rainbows, etc and What are some interesting optic instruments? eg microscope, telescopte, camera etc
Asked by MS - Sat Mar 10 19:07:05 2007 - - 3 Answers - 0 Comments
A. Optics is great. Some great phenomena is reflection which we use for fiber optic cables. The light beam just bounces around in the cable. Another is refraction which we can use to seperate the light could be used in fiber optics or as an optical switch. LCD technology use a number of optical principles from polarizers to refraction to get colors some interesting instruments are sunglasses or ski goggles because they have polarizers and are anti-reflective (Maui Jim's rock!). LCD screens of course and fiber optic cables. There is also optical switches

How can one explain prism dispersion by using nonlinear optics?
Q. We all know, that prism disperses white light. We also can obtain mathematical relation between wavelength and deflection angle by using simple linear optics. But I recently heard that the prism itself somehow affects the way light travels through it and that is the question of nonlinear optics. So how can one explain this effect by using nonlinear optics?

A. In linear optics, the medium is essentially a fixed quantity. That is, the strength of the light beam's electric field is very low, and essentially has no effect on the medium's response to the light. In nonlinear optics, the light beam's electric field is strong enough that it actually affects how the medium responds to the light. Hence nonlinear, because the light affects the medium which affects the light. These effects only occur in normal materials with very intense light, or in certain special materials which can usually be easily polarized. As a conceptual example, I'll use nonlinear sound waves in water: For a sound wave of normal intensity, the water molecules are locally slightly compressed and slightly expanded as the… [cont.]

It is more and more used for home Internet, the big towns increasingly change the old cables in fiber optics to provide a much bigger data transfer speed. And fiber optics are used for about a decade or more for oversea communication, Big fiber optics are crossing the oceans to provide fast communications.

Where can I find information on Optics?
Q. I am looking for some information on some optics I was given. The box contains a metal slide holder with a built in probe. It also contains a tube with a lens marked EDSCORP on one side and 10 0.25 JAPAN. on the other. There are also two other lenses that are unmarked. I would like any information on these optics or help in finding information. They came from an old science classroom and I have no idea on how old they are. Everything is in excellent condition. There is a little tarnish on the slide holder, and the two smaller lenses show signs of use, but the tube and larger lens very clean.
Asked by Charlie - Tue Jul 4 19:48:59 2006 - - 2 Answers - 0 Comments
A. As you have two unmarked lenses you'll never find out about them from a book/manufacturers charts/the web. You'll need to test them yourself. Fortunately it's very easy to test them to find out their properties. Focus is easy shine light through and see where it converges. More accurate testing of this can be done with a laser and observing speckle patterns. Once you know the focus measure the curvature and from that you can calculate the refractive index of the lens.

How do fiber optics work?
Q. I know fiber optics are made of glass, but how do they get them to bend in a cable? it is just a property of glass to be flexible when its in really thin rods or what?
Asked by Daniel C - Thu Feb 15 06:08:20 2007 - - 2 Answers - 0 Comments
A. In practical fibers, the cladding is usually coated with a tough resin buffer layer, which may be further surrounded by a jacket layer, usually plastic. These layers add strength to the fiber but do not contribute to its optical wave guide properties. For indoor applications, the jacketed fiber is generally enclosed, with a bundle of flexible fibrous polymer strength members like Aramid (e.g. Twaron or Kevlar), in a lightweight plastic cover to form a simple cable. Each end of the cable may be terminated with a specialized optical fiber connector to allow it to be easily connected and disconnected from transmitting and receiving equipment. For use in more strenuous environments, a much more robust cable construction is required. In loose- [cont.]

A. it is a long filament of special fiberoptic plastic. The long side gathers the light, and channels it to each end, this makes the end appear quite bright. it does NOT glow in the dark, for that you need trijon night sights or some other similar product that uses mildly radioactive materials to make it glow for years. Most fiberoptics sights aren't peep holes at all, they are either just a front sight so the font sight dot is brighter, or they are front and rear, where the 2 dots on the rear sight are also brighter

Physics and optics: A point source of light is submerged 2.4 m below the surface of a lake?
Q. A point source of light is submerged 2.4 m below the surface of a lake and emits rays in all directions. On the surface of the lake, directly above the source, the area illuminated is a circle. What is the maximum radius that this circle could have?
Asked by Hera08 - Wed Dec 5 22:44:25 2007 - - 1 Answers - 0 Comments
A. Let the radius of the circle be r m. This means that at a distance greater than r from the center of the circle, the light rays undergo total internal reflection. Assume the position of the source of light as O and the center of the circle as P. Now assume another point on the edge of the circle A. So the angle AOP is the critical angle of water with respect to air, say @. Refractive index of glass with respect to air, n = 1/ sin @ n = 1.33 Solve for @ @ = 48.59 Now tan @ = 2.4 / r 1.13 = 2.4 / r r = 2.12 m Hope this helps. your_guide123@yahoo.com

In terms of optics, what is the basic concept behind how a photocopier works?

Asked by Meli319 - Thu Jul 3 04:29:17 2008 - - 1 Answers - 0 Comments
A. There's a good explanation in the reference. Basically the surface of a rotating drum is electrostatically charged, then exposed to a bright image of the original. Where light hits the drum, the charge leaks off, resulting in an electrostatic "image" on the drum. The drum next picks up charged toner particles where the surface charges remain. This toner image is then electrostatically transferred to a blank paper and baked onto it.
