Optics is a branch of physics that involves the properties of light and its interaction with matter. Reflection, refraction and diffraction are different ways light can behave based on the conditions ...

MISSOULA, Mont. — While up in the mountains, have you ever looked down on a cloud or fog bank below and seen concentric rings of light surrounding your shadow? A viewer recently shared a photo of this ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Galaxy cluster SMACS 0723, known as Webb’s First Deep Field, ...

Fresnel diffraction describes the complex light propagation that occurs when a wavefront encounters an abrupt phase change, typically at the boundary of two different media or at an engineered phase ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

Sometimes the whole purpose of a post here is to share an especially nice photo that we ran across somewhere, especially if it also illustrates an interesting phenomenon (in this case two) occurring ...

An incredible photo was captured in southern Indiana of cloud iridescence. This photo was submitted by Bobbi Bledsoe, from French Lick, captured on Mother's Day.WLKY Chief Meteorologist Jay Cardosi ...

The dazzling spectacle unfolded in a matter of minutes, but its short-lived appearance has left an indelible mark on those lucky enough to witness it. Jenni Shaw, who was at her family-owned business ...

New diffraction phenomenon of acoustic waves. A novel asymmetric diffraction has been achieved using a nano-patterned array of ferromagnets. This demonstration arises from a unique interaction between ...
