![]() The energy-level structure depends on the nature of the potential, E n n 2, for the particle in a one-dimensional box, so the separation between energy levels increases as n increases. Particle-in-a-box models illustrate a number of important features of quantum mechanics. ![]() Zero-point energy is a consequence of the Heisenberg indeterminacy relation all particles bound in potential wells have nite energy even at the absolute zero of temperature. For example, the probability of locating the particle at a particular location is the square of the amplitude of its wave function. Once we accept that particles can behave as waves, we can form analogies with classical electromagnetic wave theory to describe the motion of particles. Wave–particle duality accounts for the probabilistic nature of quantum mechanics and for indeterminacy. Because the energy level spacing is inversely proportional to the mass and to the square of the length of the box, quantum effects become too small to be observed for systems that contain more than a few hundred atoms. The one-dimensional particle-in-a-box model shows why quantiza-tion only becomes apparent on the atomic scale. Energy quantization arises for all systems whose motions are connned by a potential well. ![]() Nonetheless, we have accepted their validity because they provide the most comprehensive account of the behavior of matter and radiation and because the agreement between theory and the results of all experiments conducted to date has been impressively accurate. These ideas appear foreign to us because they are inconsistent with our experience of the macroscopic world. The key new concepts developed in quantum mechanics include the quantiza-tion of energy, a probabilistic description of particle motion, wave–particle duality, and indeterminacy. This was undoubtedly one of the most signiicant shifts in the history of science.
