Researchers at Tampere University and the University of Eastern Finland have reached a milestone in a study where they derived a new kind of wave equation, which applies for accelerating waves. The ...

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to get there. When you purchase through links on our site, we may earn an ...

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the ...

Perhaps the most iconic instrument in modern rock is the guitar. It's really just a bunch of strings stretched across a board, which you can strum to make awesome tunes, thanks to the physics of waves ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a ...

Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel H. Devoret and John M. Martinis "for the discovery of ...

Down at the level of atoms and electrons, quantum physics describes the behavior of the very smallest objects. Solar panels, LED lights, your mobile phone and MRI scanners in hospitals: all of these ...

Whenever light interacts with matter, light appears to slow down. This is not a new observation and standard wave mechanics can describe most of these daily phenomena. For example, when light is ...
