Wave function

A wave function in quantum mechanics describes the quantum state of a particle or system. It provides information about the probability amplitude of finding a particle in a particular position or state when measured. The wave function is usually represented by the Greek letter psi (ψ) and its square (|ψ|²) gives the probability density of the particle's location. This concept is fundamental to understanding phenomena like superposition and quantum interference.
