wave function

A wave function is a mathematical description used in quantum physics to represent the state of a particle, like an electron. It contains information about the probabilities of finding the particle in different places or states. Instead of giving a specific location, it provides a "spread" of possibilities. When you measure the particle, the wave function 'collapses' to a particular outcome. Think of it as a tool that predicts where a particle might be, rather than a definite position until observed. It’s fundamental to understanding how particles behave at very small scales.
