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. When you purchase through links on our site, we may earn an ...

Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field.

For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'. When you ...

However, light's double nature, known as wave particle duality, is absolutely fundamental to the existence of the world as we ...

EPFL scientists have developed a new technique that lets researchers watch, with unprecedented sensitivity, how materials ...

Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can ...

The principle of wave-particle duality is crucial in quantum physics, highlighting the dual nature of light and matter and ...

Where the crest of one wave overlaps with the crest of the other, you get constructive interference and a patch of light. Where a crest meets a trough, you get destructive interference and darkness.

The original waves. In 1924, French physics doctoral student Louis de Broglie proposed that matter has a wave-like property. De Broglie was inspired by the discovery of wave-particle duality in light.
