Significance of Wave Function in Physics
The probabilistic nature of quantum phenomena is also represented by a wave function, which given the state of a particle describes the amplitude of its position, momentum or other physical property. It evolves to conform to the Schrodinger equation and it holds all the measurable knowledge concerning one quantum system. The square of the size of the wave function determines the probability density that guides expectations on the result of the experiment. The complexity of quantum behavior allows the two key features of quantum behavior, namely superposition and interference. The wave function forms a central element of modern physics and a powerful asset in the theoretical and applied quantum mechanics; this is because one must understand the atomic, molecular and subatomic physical processes.
