A recent study published in an online issue of Physical Review Research examines the connections between the different properties of light, specifically pertaining to whether light acts as a wave or ...

Researchers exploring the interactions between light particles, photons and matter find that optical microresonators host quasiparticles made by two photons. Scientists at the University of Bath in ...

Slowing down light is not as easy as it sounds. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The phenomenon of light slowing down as it passes ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

Even diffuse objects like clouds or sugar cubes cast shadows, because they’re disordered media that scatter light waves. But now, researchers at TU Wien and Utrecht University have found a way to ...

Light propagating in an optical fibre can make a tiny glass sphere nearby twist around on its axis. A theoretical analysis now explains why — and unexpectedly shows that the effect does not require ...

The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin's Broome Bridge in 1843. Subscribe to ...

Physicists have discovered that when beams of light interact at the quantum level, they can generate ghost-like particles that briefly emerge from nothing and affect real matter. This rare phenomenon, ...

It's an age-old question and one that any meteorologist hears quite often. Why is the sky blue? It has to do with light waves and how they travel through our atmosphere. The light from our sun travels ...
