The visible light spectrum detectable by human eyes makes up only a small fraction of wavelengths (0.0035%, to be exact). Those colors are made available to us by millions of densely packed ...

Colors with extremely short wavelengths, like violet and blue, scatter out much easier due to their short wavelengths. This “scattering” effect is what creates our color in the sky!

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 ...

Violet light, at wavelengths less than 450 nm, is associated with a higher degree of light scatter and may have phototoxic effects that increase the risk for retinal disease.

With blue and violet light having shorter wavelengths, they’re most likely to be scattered by air and dust particles. As the distance increases, it’s the long wavelength colors that make it ...

Violet is a single wavelength close to 380 nm, at the limit of what our eyes can see. Why Is the Sky Colored, Anyway? If the sun produces white light, why do we see any colors in the sky at all?

Anyone who ever ended up with a sunburn knows violet wavelengths are real, as the Sun’s ultraviolet (UV) radiation is the reason you need to wear sunscreen, even though you can’t see those ...
