In fact, violet (along with the rest of the colors in a naturally occurring rainbow) has something purple doesn’t—its own wavelength of light. Anyone who ever ended up with a sunburn knows ...

Ultraviolet has very short and energetic wavelengths that are shorter than violet on the visible spectrum. But can people see UV? When you purchase through links on our site, we may earn an ...

As a result, purple and magenta are known as "nonspectral" colors, because they don't really exist as actual electromagnetic radiation. Nonspectral colors like purple are made of two wavelengths of ...

Visible' light-emission device technology is reaching its maturity, and many groups have shifted their research focus towards the shorter-wavelength UV devices. This interest is fuelled by the ...

Because UV light with wavelengths less than 360 nm does not penetrate the eye’s cornea, this suggests that our eyes sense and adapt to the deep violet visible wavelengths in natural light.

Biofluorescent creatures generate their glow with structures that absorb high-energy wavelengths of light, such as UV, violet or blue, then emit the light in a lower-energy wavelength. Researchers ...
