Three RIKEN physicists have discovered how tiny tubes of carbon spit out light that is more energetic than the light shone on them. This finding could help to exploit the process in applications such ...

That’s quite a big gap, as it turns out. It covers fields from gigantic bodies like the Sun and Earth, as well as those ...

A new method finally reveals the full quantum identity of electrons, offering insights that could transform material science ...

Brave New World is about to hit cinemas, bringing with it the gamma-ray-powered Red Hulk. Here's what you need to know about ...

Radiation within the visible spectrum can appear black if it is low in power – more specifically, lower in power than its ...

GIA’s laboratories use advanced instrumentation and research to deliver accurate grading, identification, and origin ...

These dips can be used to detect an orbiting planet, and the timing between dips in light can be used to help scientists determine how long it takes the newly discovered world to orbit its star.

Terahertz light lies in a part of the electromagnetic spectrum between microwaves and infrared ... with the atomic and molecular vibrations of materials. Unlike X-rays or ultraviolet light, terahertz ...

Using this approach, they successfully reduced optical noise across a broad spectrum—from visible light to ultraviolet wavelengths—and demonstrated high-numerical-aperture (NA) metalenses and ...

To understand where black falls on the color spectrum, first consider what light actually is. Light is radiation visible to the human eye Light is energy called electromagnetic radiation.
