Successive energy measurements
This animation shows the effect of a first and a second energy measurement on an initial superposition of states describing a quantum particle in a 1D infinite square well potential. The user can take several measurements, seeing how the superposition collapses into different eigenstates. A "step-by-step exploration" tab explains the key points. The animation can be downloaded.
