In quantum mechanics, the particle in a box model (also known as the infinite potential well or the infinite square well) describes a particle free to move in a small space surrounded by impenetrable barriers. The model is mainly used as a hypothetical example to illustrate the differences between classical and quantum systems. In classical systems, for example, a particle trapped inside a large box can move at any speed within the box and it is no more likely to be fou… WebParticle in a 3D Box (3) The energy eigenstates and energy values in a 3D cubical box are: where n x,n y, and n z can each have values 1,2,3,….
