Astronomers have spotted another never-before-seen "nova" blaze to life in the night sky. This may be the first time that ...

For example, blue and violet photons have more energy than ... They can see light in the infrared spectrum as well as the visible color spectrum. Scientists can take pictures of Mars in the infrared ...

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

Electromagnetic Spectrum Is More Important Than You Think. Here’s Why It plays a significant role in our lives. Updated: Jun 04, 2025 03:39 AM EST ...

Our eyes only perceive a narrow sliver of the spectrum—wavelengths between 400 and 700 nanometers make up what we call “visible” light. Infrared light, just beyond the 700-nanometer mark, is invisible ...

Black doesn’t appear in the visible spectrum of electromagnetic radiation. So why do we still see it?

Radiation within the visible spectrum can appear black if it is low in power – more specifically, lower in power than its surroundings. Additionally, radiation outside the visible range of wavelengths ...

UV–vis spectroscopy is a workhorse in analytical chemistry that finds application in life science, organic synthesis, and energy technologies like photocatalysis. In its traditional implementation ...

The Rec. 2020 gamut, also referred to as the BTU2020, covers an impressive 75% of the visible light spectrum. That’s a nearly 40% jump from DCI P3 and an even more significant leap from sRGB.

"This is the first example of infrared quantum dots that are at the same level of quality as the ones that are in the visible spectrum," Smith says.
