In quantum mechanics, particles such as electrons exhibit wave-like behavior, described by the concept of wave functions. These wave functions represent the probability of finding a particle in a particular location and are governed by the Schrödinger equation. This dual nature of particles is a fundamental principle of quantum mechanics, illustrating that they can behave both as particles and as waves. The wave aspect of particles leads to phenomena like interference and diffraction, which are typically associated with classical waves. This wave-particle duality is essential for understanding various quantum phenomena, including the behavior of atoms and the principles behind technologies like quantum computing and semiconductors.
