As a result, purple and magenta are known as "nonspectral" colors, because they don't really exist as actual electromagnetic ...

A prism can break white light up into the visible light spectrum. (Image credit: NASA) A spectroscope or spectrometer splits light into the wavelengths that make it up.

visible spectrum says: July 6, 2016 at 6:41 am I guess 300nm to 390nm or 700nm to 1000nm is part of the visible spectrum and we’re just not trying hard enough?

For example, the bright hue of a Red Delicious apple, which has absorbed the blue, orange, yellow, ... Absent from the visible spectrum and neither a wave nor a particle, the color pink is, ...

Discovered more than a century ago, the electromagnetic spectrum is the basis on which our universe operates. Without it we wouldn’t be able to see, stars wouldn’t shine, and life would not exist.

This scanner also has a decided advantage over X-ray CT scanners in that it can image the outside of an object in the visible spectrum, which makes it a handy 3D-scanner in addition to its use in ...

That expands the spectrum of the standard LED to the wavelength range of 380 nm - 780 nm, thus providing sufficient light intensity over nearly the full visible light (Fig. 1, red line).

Beyond just the market demand for visible spectrum nanocrystals, chemistry is harder for materials in the infrared, which is longer wavelength and lower energy than light in the visible spectrum.
