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 ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

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 ...

The concept of light has fascinated scientists for centuries. A recent MIT experiment has reignited the debate about its dual nature. The MIT team revisited a classic experiment with unprecedented ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

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 ...

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 ...
