A measurement X collapses the wave function randomly into an eigenstate of X. Then if a different measurement Y is made the wave function will randomly collapse into an eigenstate of Y. So for example if you measure position, the wave function will collapse into a narrow peak. Now if you measure momentum, the wave function will collapse into a spread out wave.
Are all eigenstates like that? Or are there examples of eigenstates where if you make repeated measurements, it stays the same?
