Live Science on MSNDoes the color purple really exist?The world is awash with the color purple — lavender flowers, amethyst gemstones, plums, eggplants and purple emperor butterflies. But if you look closely at the visible-light portion of the ...
Bup bup bup — no, violet is actually a completely different color, scientifically speaking. Like all other colors in the spectrum (and hence in the rainbow), it has its own wavelength and ...
Violet is a real spectral color, while purple is fake and exists only as a mix of red and blue light. There’s no pure “purple” wavelength, which is why it’s left out of the rainbow entirely.
There’s no single wavelength that carries it, so one’s brain fills in the blank. So there you have it — sorry to upend your conception of reality.
But purple? Well, purple is just your brain’s way of resolving confusion. That’s right. Red and blue (or violet) wavelengths are two opposite extremes on the spectrum.
Sunlight consists of a spectrum of colors, each with a different wavelength. Violet has the shortest wavelength and bends the most, while red has the longest wavelength and bends the least.
Red, orange and yellow have longer wavelengths, which means, in short, they have a better chance of making the long journey. -Wildfire smoke that turns the sky a hazy orange.
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.
Visible light has wavelengths that can be perceived by the human eye, with the longest being red and the shortest being that of violet or blue. A red light wave is about 750 nanometers, while a ...
