Optic lenses are substances that allow light to pass through them while manipulating its density or its trajectory. They are typically made from glass or plastic, but can be constructed from any material that is clear enough to allow at least some light to pass through it. The purpose of optics is to either project an image onto a... more »
Fiber optic cables are being used more frequently to transmit cable TV, provide Internet access and make phone service available to homes and businesses. Fiber optic may seem like new technology, but has in fact been around for centuries, and the cables offer many advantages over copper. more »
Flip Video is a brand of compact digital camcorders designed for people who want a pocket-sized affordable camcorder. The camcorders typically don't have all the bells and whistles of other camcorders on the market, but are also available at astoundingly low price, making the spec compromise often worth it for some consumers. more »
For much of the 20th century, communication technologies relied on conventional copper and metal wirings. With the emergence of optical fibers has come a new medium on which to transmit massive amounts of information. Fiber-optics technology has revolutionized the communications world with faster transmissions that carry significantly... more »

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.McGrawHill> 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.McGrawHill />
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 lights 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 f read more at » http://en.wikipedia.org/wiki/Optics
