WXMI — In our science experiment today, we look at a disappearing coin trick, which really is no trick at all. It illustrates density and refraction. Some things are more dense (or heavier) than ...

(Photo Credit: Ray Petelin) This seems rather basic, but how light interacts with different things can be very, very interesting. Light can bounce off things. That is called reflection.

The film explores the properties of light, including reflection and refraction, through various experiments. It demonstrates how light travels in straight lines, how mirrors can reflect images ...

Refraction—the bending of light as it passes through different media—has long been constrained by physical laws that prevent ...

Dark matter, a type of matter that does not emit, absorb, or reflect light, is predicted to account for most of the ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. Known as “spacetime wave packets,” these lasers follow different rules of refraction ...

According to Fermat's principle about the refraction of a ray of light, the light bends when it meets a matter with different refractive indices and travels through time-minimizing paths.

An experiment on the side of an extinct volcano in Mexico involving gamma rays is helping scientists answer a fundamental question in physics: Is the speed of light the same throughout the ...

The inside lens bends the rays a little, but it can't make up for the lost corneal refraction, so the light that reaches the retina isn't focused and the underwater world looks blurry.
