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 ...

Light propagation is usually reciprocal meaning that the trajectory of light travelling in one direction is identical from that in the opposite direction. Breaking reciprocity can make light propagate ...

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 ...

With morning and nighttime routines alone, people spend plenty of time looking in the mirror, but did you know the history of this everyday item dates to 4000 B.C.? According to Brown University’s ...

Two separate teams of scientists have built the thinnest mirrors in the world: sheets of molybdenum diselenide (MoSe2), each just a single atom wide. The mirrors were developed at the same time at ...

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 ...

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 ...

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 ...
