how can we calculate the amplitude of a one dimentional harmonic oscillator using wave function?
There's no amplitude, but probability amplitude to obtain spectral values of a certain observable being measured.
but how can we get close to the classical significance "Oscillator Amplitude"?
The coherent states follow most closely the classical motion of a linear harmonic oscillator.
if we want to examine a classical harmonic oscillator by quantum approach, how should we regard the most displacement from center?
