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. [1] Optics usually describes the behaviour of visible, ultraviolet, and infrared light.
An illustration of some of the optical devices available for laboratory work in England in 1858. An optical instrument is a device that processes light waves (or photons), either to enhance an image for viewing or to analyze and determine their characteristic properties.
Optical phenomena encompass a broad range of events, including those caused by atmospheric optical properties, other natural occurrences, man-made effects, and interactions involving human vision (entoptic phenomena).
The optical properties of matter are studied in optical physics (a subfield of optics) and applied in materials science. The optical properties of matter include: Refractive index; Dispersion; Transmittance and Transmission coefficient; Absorption; Scattering; Turbidity; Reflectance and Reflectivity (reflection coefficient) Albedo; Perceived ...
Optics is a broad subject area. Much of the content is covered in subcategories. Many basic concepts are covered in Category:Geometrical optics, in which light is considered as if it were composed of rays. Articles dealing with the wave nature of light can be found in Category:Physical optics.
The optics used is a type of Mangin mirror system, consisting of a meniscus lens corrector element combined with the semi-reflective mirror, sometimes referred to in advertising as a "two lens" or "double lens" system.
During Tuesday's trial, Whitefeather insisted the shed was a "teenager hangout," per the AP, testifying, “They weren’t locked in … They had a key.
The optic or non-drip measure is mounted beneath an inverted spirit bottle, so that a pre-defined volume of the bottle's contents drains into the measure. Lifting a lever on the side of the measure first closes off the measure from the bottle, then dispenses the measured liquid into the glass or mixing vessel held underneath.
