Light is everywhere,it illuminates our world, enables vision, and travels across galaxies. But what is light, really? Is it a wave or a particle? The answer is both,and neither, depending on how ...

The wave-particle duality is one of those essential pillars. Physics courses devote weeks to just introducing it – but there are still important aspects that can be covered in a short article.

Wave-particle duality is a cornerstone of quantum mechanics, which is our modern theory of how subatomic particles behave.

In the traditional formulation of quantum mechanics, when a particle is measured -- meaning it is found to be in one particular location -- the wave function is said to collapse.

But until we figure out a way to test quantum gravity using gravitational waves, we won't know whether the "particle" part of wave-particle duality holds for gravitons.

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

The double-slit experiment was designed to investigate whether light is a wave or a particle. It is one of the most famous and weirdest experiments in physics.

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.

The classic quantum mechanics problem is a particle in a 1-D box. Here is a numerical solution to that problem.
