Researchers at the Dalian University of Technology and the University of Hong Kong have developed a novel method for creating dynamically ...

Imagine a future where you could see in complete darkness — not through bulky night vision goggles, but with nothing more ...

Discover how researchers are using Tamm plasmonic photonic crystals and antimony trisulfide to create reconfigurable color ...

Vexlum overcomes these challenges by relying on Yokogawa’s optical spectrum analysers (OSAs), which combine two capabilities: ...

Earlier, and perhaps more basic, LED masks usually provide just one primary colour treatment mode, such as red or blue, ...

In this letter, we present indoor multipath dispersion characteristics for visible light communications (VLC). Since the VLC uses a wide spectrum between 380 nm and 780 nm, the conventional narrowband ...

According to Schlesinger, iron oxide used in tinted sunscreens can protect a large portion of the visible light spectrum, all the way up to 700 nm, including blue light.

Considering the full light spectrum The scientists faced challenges in studying the role of far-red light in photosynthesis because existing models only considered visible light (400–700 nm) as the ...

But the problem is that the current definition of UV-A 315-400 nm ultraviolet light includes a critical part of the healthy light spectrum: 360-400 nm deep visible violet light.

The visible light spectrum ranges from wavelengths of ~400 to 700 nm, and UV light has shorter wavelengths of between 100 to 400 nm.

Their light interaction gives the illusion of purple but doesn’t change the fact that purple doesn’t have its own distinct wavelength in the visible spectrum.
