Earlier, and perhaps more basic, LED masks usually provide just one primary colour treatment mode, such as red or blue, ...

Infrared spectroscopy measures IR emissions from materials at specific wavelengths. The IR spectrum of a substance will show characteristic dips and peaks as photons (particles of light) are ...

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.

A new filter for infrared light could see scanning and screening technology tumble in price and size. Built on nanotechnology ...

“We’ve demonstrated that we can confine infrared light to 10% of its wavelength while maintaining its frequency—meaning that the amount of time that it takes for a wavelength to cycle is the ...

Infrared light—light whose wavelength is longer than our eyes can detect—exists all around us. But we do not see it. Yet. Scientists have engineered some proteins to “see” infrared. New ...

Infrared light has longer wavelengths than visible light, and we can feel it as heat. In fact, some animals, like snakes, can see in the infrared part of the spectrum! Visible light is what we can see ...

As the wavelength increased into the infrared (IR), participants found the light at first harder to detect, but at around 1,000 nm the light became easier to see. How humans can do this has ...

As light travels through space, it gets stretched by the expansion of the universe. This is why many of the most distant objects shine in infrared light, which is longer in wavelength than visible ...

They assign various infrared wavelengths to colors on the visible spectrum, the familiar reds, blues, yellows, etc. But while the processed images from the Webb team aren’t literally what the ...
