Is light a wave or a particle? Well, it's not a particle. The photoelectric effect can be explained with a wave model for light and a quantum model for matter.

Newton insisted that light was a particle-like ray — a corpuscle, in his words — pointing to phenomena like the refraction of light through a crystal.

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.

Scientists Produced a Particle of Light That Simultaneously Accessed 37 Different Dimensions It’s got us beat by 34.

After three years of scrutinizing the elusive Higgs boson closely, scientists say they've determined that the "God particle" behaves just as predicted.

Scientists in Switzerland have managed to take a snapshot of light in all its elusive wave-particle duality.

Essentially, an international team of scientists wanted to see how un -classical particles of light could get—and the results were maybe stranger than the authors originally anticipated.

For the first time, physicists have captured light acting as both a wave and a particle in the same snapshot.

Introduction You may have heard that light consists of particles called photons. How could something as simple as light be made of particles? Physicists describe light as both a particle and a ...

According to a new Apple patent, the iPhone's Apple logo could one day double as a notification light. The patent suggests that the logo, described as an adjustable decoration, could have multiple ...

Researchers have achieved the first ever pictorial evidence that light can simultaneously behave as a particle and as a wave.

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.
