Introduction
The Double‑Slit Experiment in Modern Science
The double‑slit experiment is one of the most significant empirical foundations of quantum mechanics, demonstrating behavior that defies classical concepts of particles and waves. At its core, it reveals how entities such as photons and electrons exhibit interference patterns that cannot be explained by classical trajectories alone. This experiment, first formulated in the early 19th century and refined through 20th‑ and 21st‑century quantum physics research, continues to unlock conceptual insights into the nature of superposition, measurement, and information in quantum systems.
