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 ...

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 ...

According to quantum mechanics, the physics theory that describes the zoo of subatomic particles, all matter can be described as both particles and waves. But is it real? When you purchase through ...

Ideas from quantum physics have seeped into popular culture over recent decades in a way they failed to for the first half ...

The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. This article is more than 4 years old. Light is well known to exhibit ...

The heart of quantum mechanics is the wave-particle duality: matter and light possess both wave-like and particle-like attributes. Typically, the wave-like properties are inferred indirectly from the ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Scientists have long known that light can behave as both a particle ...

From the most distant stars in the sky to the screen in front of your face, light is everywhere. But the exact nature of ...

I HAVE been able to show that there does not exist a mutually definite correlation between the spin and the transformation properties of the wave function of an elementary particle, as generally ...
