For some time, we have known that light is both a particle and a wave. At least, it behaves like a particle and a wave; however, seeing both at the same time is no easy feat. For decades, scientists ...

Ever since Democritus – a Greek philosopher who lived between the 5th and 4th century's BCE – argued that all of existence was made up of tiny indivisible atoms, scientists have been speculating as to ...

A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in ...

According to the studies of quantum mechanics, light can act simultaneously as a particle and a wave. However, scientists have never been able to capture light in both of its forms at the same time— ...

Now that LIGO has detected their first gravitational wave signal, the part of Einstein's theory that predicts that the fabric of space itself should have ripples and waves in it has been confirmed.

Light's behavior seems counterintuitive. That is, until you figure out light is a wave. The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the Massachusetts Institute of Technology (MIT) have performed a daring experiment using ...

Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...
