Researchers from Linköping University together with colleagues from Poland and Chile have confirmed a theory that proposes a ...

Wave–particle duality is the concept in quantum mechanics that every particle or quantum entity may be described as either a particle or a wave. It expresses the inability of the classical concepts ...

The wave-particle duality is one of those essential pillars. Physics courses devote weeks to just introducing it – but there ...

The inherent contradiction in the way energy behaves. At the turn of the 20th century, it was believed that light was electromagnetic waves and electrons were particles. By the 1930s, it was ...

In classical optics, for instance, a brighter light has more energy, and a greater amplitude of its electromagnetic wave. But, when it comes to ejecting an electron from a material via the ...

Photoemission is a process during which electrons are ejected from a metal surface when exposed to electromagnetic radiation, (eg ultraviolet). If a clean, positively charged zinc plate is exposed ...

That light can be both particles and waves is one of the most illogical – but at the same time fundamental – characteristics of quantum mechanics. This is called wave-particle duality. The theory ...

The double-slit experiment, termed “the quantum experiment that broke reality,” demonstrates the paradoxical wave-particle ...

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 ...
