The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light. [2] In some cases caustics can be seen as patches of light or their bright edges, shapes which often have cusp singularities .
Caustic embrittlement is the phenomenon in which the material of a boiler becomes brittle due to the accumulation of caustic substances. [1] Cause
Caustic may also refer to: Caustic (band), an American industrial/powernoise band; Caustic (mathematics), the envelope of rays reflected or refracted by a manifold; Caustic (optics), optic phenomenon due to light rays reflecting/refracting through curved surfaces/objects; Caustic Graphics, a graphics technology developer, part of Imagination ...
Gravitational microlensing is an astronomical phenomenon caused by the gravitational ... Caustic crossings in binary lenses can happen with a wider range of lens ...
mild steel cracks in the presence of alkali (e.g. boiler cracking and caustic stress corrosion cracking) and nitrates; copper alloys crack in ammoniacal solutions ( season cracking ); high-tensile steels have been known to crack in an unexpectedly brittle manner in a whole variety of aqueous environments, especially when chlorides are present.
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide.It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment.
In optics, spherical aberration (SA) is a type of aberration found in optical systems that have elements with spherical surfaces.This phenomenon commonly affects lenses and curved mirrors, as these components are often shaped in a spherical manner for ease of manufacturing.
Reflective caustic generated from a circle and parallel rays. On one side, each point is contained in three light rays; on the other side, each point is contained in one light ray. In differential geometry, a caustic is the envelope of rays either reflected or refracted by a manifold. It is related to the concept of caustics in geometric optics ...
