particle in a box

"Particle in a box" is a quantum physics model describing a tiny particle confined within a fixed, impenetrable space, like a tiny chamber. Because of quantum mechanics, the particle can't have any energy, only specific, discrete levels—like stepping stones—inside the box. It cannot escape, and its exact location is uncertain, but its energy states are well-defined. This model helps scientists understand phenomena at microscopic scales, such as electrons in atoms, by illustrating how confinement leads to quantized energies, highlighting the wave-like nature of particles at the quantum level.
