How does color work, and how does the type of light source you use affect the colors you see? Appliance Science looks at the science of light and color. Richard Baguley Richard Baguley has been ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

Visible light travels in electromagnetic waves, which we see as the colors of the rainbow. Different colors have different wavelengths of light. Violet and blue have the shortest wavelengths, whereas ...

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 ...

Join hosts Evie and Garrett as they learn more about light and color! Light is energy. It illuminates and colors our world, but there is more to light and color than the eye can see. Science Trek ...

Scientists have developed a fast and extremely efficient method for transferring huge amounts of data. The technique uses dozens of frequencies of light to transfer several streams of information over ...

The sky above San Francisco was the color of television, tuned to the president. The reason for the orange—and for the wan yellows and sickly grays that followed—is a combination of atmospheric ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

Physicists and vision scientists are lining up behind a provocative claim: the rich color we call purple is not a property of light at all, but a story the brain tells itself. Light in the real world ...
