double slit
Paired narrow openings
The double slit refers to a famous physics experiment demonstrating the wave-particle duality of light and matter.
When particles or light pass through two narrow parallel slits, they create an interference pattern on a screen behind—as if waves were passing through and overlapping.
The experiment reveals that quantum objects behave as waves until observed, then appear as particles: The double-slit experiment changed our understanding of reality.
