The experiment showed that Bohr was definitely correct when he argued for complementarity, and that Einstein had got it wrong. The more atom-rustling that was measured, the weaker the diffraction ...

(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.

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.

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 ...

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