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 ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

Wave-particle duality is a fundamental fact of the Universe. But we don’t see many objects moving around as waves. This is why it hurts when a golf ball hits you on the head: you and the golf ball are ...

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

Light’s dual nature, manifesting as both wave-like and particle-like behaviour, is a phenomenon known as wave-particle duality and remains one of the most perplexing mysteries in quantum mechanics.

Photon duality remains a paradox because the photon is regarded as a simple, unitary object in space. Equally bad, massless radiation is interpreted via concepts drawn from mass-based physics. The ...

Artist's impression of single photons' behavior when passing through an interferometer having a quantum beam-splitter at its output. In the back of the picture, sinusoidal oscillations are observed, ...
