The 22° Halo is a striking optical phenomenon that manifests as a circular ring of light around the sun or moon. This halo is formed by the refraction of light through ice crystals in high ...

That's called a sun pillar. According to the National Weather Service, the optical phenomenon appears as a vertical shaft of light, visible most often at sunrise or sundown. SEE ALSO: Sunshine and ...

as well as Imperial College London and University College London suggest leveraging an optical phenomenon called chromatic aberration—that usually degrades image quality—to produce suitable ...

Optical illusions are a striking phenomenon that regularly goes viral online, leaving all and sundry baffled. These interesting photos fool our brains ...

Some optical phenomena depend on the quantum nature of light and the interaction of light with matter. Geometric optics and physical optics are models that describe phenomena while ignoring properties ...

Physicists at the University of Ottawa add an orbital spin to their laser beams to control the movement of electrons in their ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...

Scientists suggest leveraging an optical phenomenon called chromatic aberration -- that usually degrades image quality -- to produce suitable images with standard microscopes. Quantitative phase ...
