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 ...

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 ...

The double slit experiment reveals that observing light changes its behavior, making it act as both a wave and a particle.

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 ...

Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists have ...

It’s a fundamental property of the universe, and one that continues to blow people’s minds: photons behave as both particles and waves, matter and energy. Photons aren’t alone in this—every elemental ...

The weird way that light can behave as both a wave and a particle has been known to physicists for about a century, but a team in Lausanne has only now managed to capture it doing both at the same ...

Sam Baron receives funding from the Australian Research Council. Hi Ishan! Thanks for your great question. Light can be described both as a wave and as a particle. There are two experiments in ...

Physicists have theorized for over a century that light acts as both a particle and a wave, depending on the conditions, but they've never been able to capture it being both at once — until a team in ...

From the most distant stars in the sky to the screen in front of your face, light is everywhere. But the exact nature of light, and how it travels, has long puzzled scientists. One question in ...

It’s in your physics textbook, go look. It says that you can either model light as an electromagnetic wave OR you can model light a stream of photons. You can’t use both models at the same time. It’s ...

Classically, light can be thought of in two ways: either as a particle or a wave. But what is it really? Well, the ‘observer effect’ makes that question kind of difficult to answer. So before we get ...
