The Wave-Particle Duality of Matter

The wave-particle duality of matter is a fundamental principle in quantum mechanicsThe theory used to describe the behaviour of very small particles (atomic and subatomic level). Unlike classical physics which is deterministic, quantum mechanics is a probabilistic theory., the branch of physics that describes the behavior of matter at the atomic and subatomic level. It was first proposed by Louis de Broglie in the early 20th century and was later confirmed through a series of experiments.

It states that particles of matter, such as electrons and atoms, can exhibit both wave-like and particle-like properties. This means that particles can behave like waves, with properties such as frequency, wavelength, and interference, as well as like particles, with properties such as mass and energy.
