The 'Particle in a box' is a fundamental quantum mechanics model that describes a particle free to move in a small, confined space with impenetrable boundaries, illustrating quantized energy levels and wave functions. It serves as a simplified system that helps in understanding more complex quantum systems and the concept of quantization in quantum mechanics.

Quantized energy levels refer to the discrete energy states that particles such as electrons can occupy within an atom, as opposed to a continuous range of energies. This concept is fundamental to quantum mechanics, explaining the stability of atoms and the discrete nature of atomic spectra.

Quantized Energy Levels

Wave functions are mathematical descriptions in quantum mechanics that encapsulate the probabilities of finding a particle in various positions and states. They are fundamental to understanding the behavior of quantum systems, as they provide the basis for calculating observable properties through operators and the Schrödinger equation.
