Examples

  • I have a particle in a box whose wave function looks like this.

  • And in fact, the wave function of the particle extends outside of the box.

  • And the next wave function looks like this.

  • This is the way the wave function changes is equal.

  • But so the wave function gives you ways of doing both of those.

  • What it tells you is how the wave function changes with angle.

  • I calculated the wave function.

  • Well, there are many ways to interpret the wave function in quantum mechanics.

  • The electron's wave function spreads over many lattice sites.

  • The wave function of an electron describes its probability distribution in an atom.

Morphology

wave + function

The noun compound is compositionally interpretable — a B1 learner who knows 'wave' and 'function' can infer it is a function related to waves (i.e. a mathematical mapping describing wave behaviour). However, the precise sense as the formal quantum‑mechanical object that encodes a system's state is technical and requires domain knowledge, so the meaning is only partially predictable from the parts.

Etymology

Wave function in physics uses the image of a wave to show where a tiny particle might be spread out and how likely it is to be found. The function is the math rule that gives the 'chance' of finding the particle, so it means 'a formula that describes a particle's possible places'.
