Concentration of light, especially sunlight, can burn. The word caustic, in fact, comes from the Greek καυστός, burnt, via the Latin causticus, burning. A common situation where caustics are visible is when light shines on a drinking glass. The glass casts a shadow, but also produces a curved region of bright light.
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 ...
The considerations made in the previous section give a proof that the caustic of a circle with light source on the perimeter of the circle is a cardioid. If in the plane there is a light source at a point on the perimeter of a circle which is reflecting any ray, then the reflected rays within the circle are tangents of a cardioid.
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 ...
Light has to pass through a larger part of the atmosphere when the sun is lower on the horizon. Red, orange and yellow have longer wavelengths, which means, in short, they have a better chance of ...
Benji is caustic, needling and selfish — the kind of guy who hogs the window seat, the shower and everyone’s attention. ... And while he nails David and Benji’s conflict in a single line ...

A typical microlensing light curve is shown below: Typical light curve of gravitational microlensing event (OGLE-2005-BLG-006) with its model fitted (red) A typical microlensing event like this one has a very simple shape, and only one physical parameter can be extracted: the time scale, which is related to the lens mass, distance, and velocity.
