"Whether light is a particle or a wave is a very old question," Riccardo Sapienza, a physicist at Imperial College London, told Live Science. As a species, we seem driven to understand the ...

However, light's double nature, known as wave particle duality, is absolutely fundamental to the existence of the world as we know it. This strange twinned behavior also extends to other quantum ...

My money is on light being a wave that displays particle-like properties under certain conditions. But this remains a controversial issue — one that takes us into the exciting realm of quantum ...

Physicists at MIT recreated the double-slit experiment using individual photons and atoms held in laser light, uncovering the ...

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 ...

Physicists describe light as both a particle and a wave. In fact, light's wavelike behavior is responsible for a lot of its cool effects, such as the iridescent colors produced on the surface of ...

This article is more than 4 years old. Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this ... More 2015 photograph. ... Fabrizio Carbone/EPFL (2015) ...

Scientists at the Ecole Polytechnique Federale de Lausanne managed to take a snapshot of light in all its elusive wave-particle duality, a form first proposed by Einstein in 1905.

Scientists have long known that light can behave as both a particle and a wave—Einstein first predicted it in 1909. But no experiment has been able to show light in both states simultaneously.

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 ...

This phenomenon, of interference, is uniquely a product of waves. The double slit experiment, and subsequent, more sophisticated analogues, established that light was a wave.
