I know that all things have wave-particle duality (even macroscopic objects). I'm fairly certian that macroscopic objects, since we observe them to be in more predictable locations, have an more irregularly shaped wavefunction that, say, photons (i.e., my wavefunction has a much higher probability amplitude where I am right now in space, though it extends elsewhere).

 

My question is how the frequency of wavefunctions is relevant--or if frequency is relevant in wavefunctions at all. It seems like a simple question, but I can't find info on this anywhere!

 

 

(For the record, I'm assuming that light, whose behavior we can easily observe/describe with waves, has a higher frequency wavefunction than other objects that, at first glance, dont appear to be waves.)

 

 

The wave function need not have a well-defined frequency. If I know either the position or momentum exactly, the wave function is a delta function.
