What are some experiments that demonstrate wave-particle duality?

Wave-particle duality, a fundamental concept in quantum mechanics, asserts that elementary particles exhibit characteristics of both particles and waves. Numerous experiments have been conducted over the years to demonstrate this intriguing phenomenon. One such experiment is the double-slit experiment, where particles (such as electrons or photons) are fired at a barrier with two slits. When observed, the particles behave as particles, creating two separate bands on a screen. However, when unobserved, they display wave-like interference patterns, suggesting that they can also behave as waves. Another experiment is the diffraction grating experiment, where a beam of particles passes through a series of parallel slits. Similar to the double-slit experiment, an interference pattern is observed on a screen, indicating wave-like behavior. These experiments provide compelling evidence for the wave-particle duality of particles in the quantum realm.
