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 ...

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 ...

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 ...

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 ...

For more than a century, scientists have known that waves can behave in ways that seem to defy common sense, from freak walls of water in the open ocean to ghostly ripples inside atoms. What has ...

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, ...

Researchers at the LIGO gravitational wave observatory used a new technique called frequency-dependent squeezing to boost weak signals above quantum noise. When you purchase through links on our site, ...

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 ...

The ancient Greeks conceived of five building blocks of matter – from bottom to top: earth, water, air, fire and aether. Aether was the matter that filled the heavens and explained the rotation of the ...
