Wave-Particle Duality: Why Matter Acts Like Both

Wave-particle duality means matter and light can behave as both waves and particles.
Light once thought to be only a wave also acts like particles called photons.
Electrons, usually seen as particles, can also create wave-like interference patterns.
The famous double-slit experiment shows electrons forming ripples like water waves.
Whether something acts like a wave or a particle depends on how you observe it.
Wave-like behavior explains diffraction and interference, while particle-like behavior explains collisions.
This duality is central to quantum mechanics, redefining how we understand reality.
Everyday technologies like electron microscopes rely on the wave nature of matter.
Photovoltaic cells use particle-like photons to generate electricity from sunlight.
Wave-particle duality shows that nature isn’t either/or—it’s both at once.
