Light and Optics word list, defined
- LIGHT /laɪt/ · noun, verb, adjective, adverb
- Light is the natural or artificial illumination that makes objects visible, especially the radiant energy perceived by the eye. It can also mean a source of illumination, such as a lamp or flame, and describes something that is not heavy, is pale or easily illuminated, or is not serious. Related: illumination, brightness, glow, pale.
- OPTICS /ˈɒptɪks/ (British); /ˈɑːptɪks/ (US) · noun
- The branch of physics concerned with the behavior of light, vision, and optical systems. In general contexts, the word can also refer to a thing’s visual appearance or the visual effect produced by its design. Related: optical science, light science.
- REFRACTION /rɪˈfrækʃən/ · noun
- Refraction is the bending of a wave, especially light, when it passes from one medium into another with a different density. More broadly, it refers to a change in the direction or character of something as it passes through a medium or system. Related: bending, deflection, redirection, deviation.
- REFLECTION /rɪˈflɛkʃən/ · noun
- A reflection is an image or representation produced when light, sound, or another wave is turned back from a surface. By extension, it means careful thought or consideration about oneself, one's actions, or a particular subject. Related: image, mirror image, reflection, thought.
- PRISM /ˈprɪzəm/ · noun
- A transparent solid with flat polygonal faces, especially a triangular prism, that refracts light into its component colours. More generally, a prism is a geometric solid with two parallel polygonal bases and parallelogram-shaped sides. Related: optical prism, transparent solid, refracting body.
- LENS /lɛnz/ · noun
- A curved, transparent or translucent piece of material, usually glass or plastic, that focuses light or forms images. By extension, the word can refer to a means of examining or understanding something, or to a lens-shaped part of the body or a geological formation. Related: glass, optic, objective, magnifier.
- CONCAVE /ˈkɒn.keɪv/ · adjective
- Curving inward like the inside of a bowl or circle, so that the surface is hollow relative to the viewer. Related: hollowed, sunken, indented, cupped.
- CONVEX /kɒnˈvɛks/ · adjective
- Curving or bulging outward, like the exterior of a circle or sphere; having a surface or boundary that curves away from the interior. In mathematics, describes a set or shape in which any line segment joining two points lies entirely within it. Related: bulging, rounded, curved outward, protuberant.
- MIRROR /ˈmɪrə(r)/ · noun and verb
- A mirror is a surface that produces a reflection of the object or person in front of it. As a verb, to mirror means to represent, correspond to, or imitate something closely. Related: reflection, looking glass, reflect, reproduce.
- PHOTON /ˈfoʊtɒn/ · noun
- A photon is the smallest discrete quantity of electromagnetic radiation, regarded in quantum physics as a particle that carries light or other electromagnetic energy. Related: light quantum, quantum of electromagnetic radiation.
- SPECTRUM /ˈspektrəm/ · noun
- The range of different wavelengths or frequencies of electromagnetic radiation, especially visible light. By extension, the word refers to a continuous range or broad variety of qualities, ideas, emotions, or types of something. Related: range, gamut, scope, span.
- WAVELENGTH /ˈwɔːvəlɛŋθ/ · noun
- In physics, the distance between two successive corresponding points of a wave, such as the distance between adjacent crests of an electromagnetic wave. Figuratively, it means a particular range of perception, experience, or way of thinking. Related: perspective, viewpoint, outlook, attitude.
