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 ...

Even diffuse objects like clouds or sugar cubes cast shadows, because they’re disordered media that scatter light waves. But now, researchers at TU Wien and Utrecht University have found a way to ...

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 ...

Researchers at Utrecht University, The Netherlands, and at TU Wien (Vienna, Austria) have created a special type of lightwaves that can penetrate opaque materials and pass through – as if the material ...
