The double-slit experiment

The double-slit experiment shows how particles like electrons or light waves behave differently depending on how we observe them. When particles pass through two tiny slits, they create an interference pattern on a screen, similar to waves overlapping. Interestingly, if we try to observe which slit the particle goes through, this pattern disappears, and particles behave more like solid objects, hitting the screen in two bands. This experiment reveals that particles have wave-like properties and that measurement affects their behavior, highlighting fundamental aspects of quantum physics and the nature of reality.
