1. optical

   Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour 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 by 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 light having both wave-like and particle-like properties. Explanation of these effects requires quantum mechanics. When considering light's particle-like properties, the light is modelled 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, in which it is called physiological optics). Practical applications of optics are found in a variety of technologies and everyday objects, including mirrors, lenses, telescopes, microscopes, lasers, and fibre optics.

1. optical

   Optical refers to anything related to light or sight, particularly in relation to the science of optics, which studies the properties and behaviors of light. It can also pertain to devices or systems that use light or manipulate it, such as lenses, telescopes, cameras, or fiber optic cables.

1. Optical

   Matt Quinn, better known as Optical, is a drum and bass producer and DJ from England. He is best known for his work with Ed Rush, fellow head of the Virus Recordings label, and as a pioneer of the techstep and neurofunk sound. His first single for Metalheadz, 'To Shape the Future'/'Raging Calm' and his collaborative material with Ed Rush, such as the Wormhole, album were archetypal developments in the style. The duo followed this debut album with The Creeps and The Original Doctor Shade, as well as countless singles and remixes. He also notably did most of the engineering and production work for Grooverider's album Mysteries of Funk. In addition, he has produced solo, and released in collaboration with many artists, including Trace, Dom & Roland, Fierce, and his brother Matrix. His music appears continuously in the WipEout series of videogames, notable for its association with electronica and electronic dance musics.

Examples of OPTICAL in a Sentence

1. James Scott, Senior Fellow, Institute for Critical Infrastructure Technology:

   As we’ve already seen with exfiltrated voter registration databases and the endless methods of poisoning manufacturer updates, manipulating DRE and optical scan machines and bypassing air gap defense, the state election official’s illusion of security is being pummeled by the reality of cyberattack.

2. Gil Dotan:

   Guardian Optical Technologies’ sensor provides all the necessary information regarding the occupants, the number of occupants, where do they sit, what is their physical size, and what is their posture even.

3. Geoff Ogilvy:

   It's an optical illusion on the second shot, it's uphill, but it looks downhill. It plays a fraction longer than you want it to. The stance you have wants you to hit a draw. But if you miss a shot with the ball above your feet, it's often to the right. And that's where all the trouble is.

4. Thomas Zurbuchen:

   More than 20 years ago, the Webb team set out to build the most powerful telescope that anyone has ever put in space and came up with an audacious optical design to meet demanding science goals, today we can say that design is going to deliver.

5. George Rieke:

   Excitement in astronomy in the last 70 years has been looking at different wavelengths, before that, all astronomy was done in optical( visible light) and looking at the universe in optical is like going to the symphony concert and only listening to one note. Now, we've got the whole symphony.
