Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...

Physicists and vision scientists are lining up behind a provocative claim: the rich color we call purple is not a property of light at all, but a story the brain tells itself. Light in the real world ...

During a total solar eclipse, people may see some strange things. Sure, there’s the main event happening in the sky (SN: 1/4/24). But the world may also look a little different on the ground. For a ...

To overcome the lack of wavelength-selective extraction in existing on-chip metasurfaces, Chinese scientists developed a novel approach by leveraging a nonlocal on-chip design based on symmetry-broken ...

Lights could soon use the full color suite of perfectly efficient organic light-emitting diodes, or OLEDs, that last tens of thousands of hours. The new phosphorescent OLEDs, commonly referred to as ...

Veronica Then wore an electroencephalogram, or EEG, cap and stood in front of a black curtain with a white square placed behind her like a target. Studio lights beamed down from the ceiling as a panel ...
