The way leaves reflect light, known as plant reflectance spectra, can illuminate the evolutionary history of seed plants, according to researchers. The researchers found that by measuring the light ...

It was a dark and stormy night. (I've always wanted to start off with that line.) You were driving home from work. The rain had finally stopped, but the roads were wet and shiny, making it difficult ...

An image printed on reflectance paper responds to the direction from which it is illuminated. The reflectance paper is covered with dimples that reflect light from different directions. See video ...

This emitted light reflects on the user's face —in the same way for each user, but different from person to person. A nearby camera records how this light reflects off the person's face, and passes ...

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 ...

Introduction You might have heard the saying “not everything is as it seems.” Something faraway might look great, but when you take a closer look it might not turn out to be as you thought it would be ...

Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a problem that’s limited imaging and display technologies for years. By ...

The way leaves reflect light can illuminate the evolutionary history of seed plants, according to an international team of scientists led by a University of Maine researcher. Plant reflectance spectra ...
