Optics is the branch of physics which studies the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behavior of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be accounted for in geometric optics. Historically, the ray-based model of light was developed first, followed by the wave model of light. Progress in electromagnetic theory in the 19th century led to the discovery that light waves were in fact electromagnetic radiation. Some phenomena depend on the fact that light has both wave-like and particle-like properties. Explanation of these effects requires quantum mechanics. When considering light's particle-like properties, the light is modeled as a collection of particles called "photons". Quantum optics deals with the application of quantum mechanics to optical systems. Optical science is relevant to and studied in many related disciplines including astronomy, various engineering fields, photography, and medicine (particularly ophthalmology and optometry). Practical applications of optics are found in a variety of technologies and everyday objects, including mirrors, lenses, telescopes, microscopes, lasers, and fiber optics. From Wikipedia under the

I just recently opened up an optical store and the location is nice but no one really sees us because we're in the middle of the Plaza and almost every business there is new. Cars ride by our building every day, but no one stops to come in. I want to know how I could advertise my business effectively without burning my pockets. Also, I want to advertise my website too, but I don't know how. Please help me. Asked by glamorglutton - Sun May 10 04:46:56 2009 - - 6 Answers - 0 Comments A. Hi there, I think your problem is a common one. There are a lot of factors to consider here, but I believe your main goal should be to create value for your local customers, but you have to be able to communicate this effectively, which is part of the problem, and around you go in this circle! Here's a link to a free e-book on exactly this topic, there's a fair bit of reading here but I'm sure it will contain at least one golden nugget you can use. Best of luck with the business.

If a camera has 12x optical zoom, and 4x digital zoom with 8.0 megapixelss is that a good camera for the price of $350? It's a Canon PowerShot S5 IS Asked by McLarney - Thu Jun 26 20:48:03 2008 - - 4 Answers - 0 Comments A. Ignore digital zoom when evaluating cameras, all it does is make lousy pictures. Optical zoom measures how much the lens can magnify your image. To use your example, a 12x optical zoom has a 12:1 zoom ratio. That means at the telephoto end, it has 12 times the magnification it has at the wide angle end. Digital zoom simply takes the pixels in the middle of your photograph and magnifies them, effectively making your 18 Megapixel camera into a five or six Megapixel camera. Shoot with optical zoom only. If you really need to magnify the center of your image, you can do it later with any picture editing software and get a better result. As to whether $350 is a good price... probably, but you don't say what model it is.

Q. I've been looking at cameras online and I want to know how far a camera with 3,4,8 & 10 optical zooms can shoot? And is it better to have a lot of mega pixels and a low optical zoom or low mega pixels and a lot of zoom? Asked by Q&A Dude - Sat Feb 14 19:18:43 2009 - - 4 Answers - 0 Comments A. Optical zoom is the difference between two focal lengths and is not the same as magnification. An example is a camera (Sanyo) with a 5X zoom using focal lengths of 5.2mm - 26mm. 26mm being the longest focal length. Another camera (Kodak) has 3X zoom using focal lengths of 35mm - 105mm. The 105mm focal length will actually get you closer (more magnification) than the 26mm focal length. So even though 10X is higher than 3X, the 3X camera will get you closer. As fopr mega-pixels, that is the size of the image and not the quality. It is true that higher mega-pixel camera images can be cropped to compensate for zoom in some instances. However, with higher mega-pixel count (on the same sensor size) you have more noise in higher ISO (lower… [cont.] Answered by Jimmy - Sun Feb 15 00:34:10 2009 From Yahoo Answer Search: "optical"  news.google.com FierceTelecom Join Mark L To power its "Managed WDM Service," KDDI is deploying ADVA Optical's FSP 3000 WDM solution.
