matter waves

Matter waves are a concept in quantum physics stating that particles like electrons and atoms can behave both as particles and as waves. This duality means that every tiny piece of matter has a wave-like nature, characterized by a wavelength related to its momentum. Think of it as particles having a "wiggle" or spread-out presence, which explains phenomena like atomic structures and interference patterns. While particles are often seen as distinct objects, their wave aspect governs their behavior at very small scales, shaping how they interact and exist in the quantum world.
