The wave function is a mathematical construct in quantum mechanics that lacks a clear physical meaning and cannot be directly measured. It evolves according to the Schrodinger equation, which is one of several equations governing quantum systems. The wave function is not an observable, but its absolute square represents the probability density of finding a particle at a specific location. Interpretations of the wave function, such as the Copenhagen and Many-Worlds interpretations, attempt to provide philosophical context to its mathematical framework. Despite the various interpretations, they yield identical experimental predictions, highlighting the complexity of understanding quantum mechanics.
