Here's the breakdown:
* The experiment: In the double-slit experiment, a beam of particles (like electrons or photons) is fired at a barrier with two slits.
* Classical physics prediction: If particles are just tiny balls, they should pass through one slit or the other, creating two distinct bands on a screen behind the barrier.
* Actual observation: The experiment showed an interference pattern on the screen – a series of bright and dark bands. This is characteristic of waves, where crests and troughs interfere with each other.
* The conclusion: This unexpected result indicated that matter, at the quantum level, exhibits wave-like behavior.
This discovery was revolutionary, leading to the development of quantum mechanics, which describes the wave-particle duality of matter.
