Thanks,Measuring Electron Wavefunction: Effects?

In summary, the conversation discusses the effects of measurement on an electron's wavefunction and whether or not it changes after observation. The conclusion is that the phase of the wavefunction will evolve over time according to the Schrodinger equation, regardless of whether photons are involved in the measurement process.

hey guys,

this is a silly question, I'm sure it's been answered in other threads many times before and for that I am sorry.

when we take a measurement on an electron (lets say position or velocity), do we change it's wavefunction? What I mean is, we have a wavefunction in time and space. it collapses to an eigenstate when we observe it. After this observation, is the wavefunction of the electron the same, or is it's phase and frequency different? (assuming in measuring it we aren't hitting it with photons or anything)

Yes, at the very least, the phase will evolve over time, according to the Schrodinger equation. Why do you require measurement to not involve photons?
