Unwanted reflections limit the performance of light-based technologies, such as solar cells, camera lenses, and light-emitting diodes (LEDs). In solar cells, for example, reflections mean less light ...

Astronomers have long been concerned about reflections from satellites showing up in images taken by telescopes and other ...

The moon will be full Thursday, which means we'll see it in all its illuminated glory. But when the moon is just a sliver, we sometimes see our own reflection shining back at us from the moon's ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. of ...

Researchers demonstrate a new technique for suppressing back reflections of light, leading to better signal quality for sensing and information technology. Researchers demonstrate a new technique for ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." For more than 50 years, scientists theorized that an electromagnetic wave could be reflected ...

Quasars are active black holes -- primarily from the early universe. Using a special method where you observe light that has been bent by gravity on its way through the universe, a group of physics ...

Sketch of the concept: a disordered medium (top) is made perfectly transmitting by placing a custom-made anti-reflection coating in front of it (bottom). (Courtesy: TU Wien) A new technique that ...

Brightfield microscopy has been widely used for hundreds of years, while reflection contrast microscopy is relatively new technology. As one of the earliest and simplest microscopy techniques, ...

A tailor-made structure may make microwave WiFi signals more transmittable through walls without reflection, according to new research. This works in much the same way as anti-reflective coating on a ...

A mother and daughter's realization of the different reflection produced by a mirror, despite a visible item not being in front of the mirror, has left the internet confused. In a viral video, the ...
