Particle in a 1D Box

This interactive simulator explores Particle in a 1D Box in Chemistry. Superposition of n=1 and n=2: time evolution of |Ψ|² and ⟨E⟩ (model units). Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Chemistry.

Key terms

  • particle
  • box
  • particle in box
  • chemistry

How it works

Infinite square well: discrete levels and spatial nodes. Interference between two energy eigenstates makes the probability density slosh back and forth — the quantum analog of beats.
