When it comes to appearances, the universe is a tricky place. Visible light occupies merely a sliver of the electromagnetic (EM) spectrum. To study the cosmos in its entirety, scientists must peer ...

Most light-field sensors — devices that detect the angles of incoming light rays to reconstruct 3D scenes — can detect light only in the ultraviolet and visible wavelength ranges. A newly developed ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

Light is more than what we see. The Sun sends out a number of waves of light in different wavelengths. Find out about wavelengths and the electromagnetic spectrum. Science Trek is available to stream ...

The human eye perceives color using three types of cones, but no natural light can stimulate just the the cones associated with medium-wavelength light in the visible spectrum. A new tool, nicknamed ...

For the past six years, the Danish-Icelandic artist Olafur Eliasson has been working with a color chemist to produce paint pigments that correspond to each nanometer of the visible light spectrum.

In a stunning breakthrough, scientists have discovered a new colour named Olo. There's just one catch: it's entirely invisible to the human eye. Defined as a deeply saturated teal, this enigmatic new ...
