When two or more light waves interact with one another, they result in the formation of different interference patterns. British physicist Thomas Young first demonstrated and explained these patterns ...

Auroras, shimmering bands of light that shoot through the night sky near the Earth’s poles, can follow patterns known as arcs ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...
