The Slits

The slits refer to a famous experiment in physics called the double-slit experiment, which demonstrates the wave-particle duality of light and matter. When particles like electrons or photons pass through two tiny openings (slits), they create a pattern of bright and dark bands on a screen—indicative of wave behavior. Surprisingly, this pattern appears even when particles are sent one at a time, suggesting each particle interferes with itself. This experiment reveals that particles behave both as particles and waves, highlighting the fundamental and intriguing nature of quantum mechanics.
