We know that momentum is proportional to k so by adding more waves(adsbygoogle = window.adsbygoogle || []).push({});

to localise our particle we are adding more waves with independent

momentum values

Upon measurement, the gaussian wavepacket must collapse into one

eigenstate of momentum, but if we have a very localised packet there will be

a great many possible momentum vales for it to collapse into

Here we have a physical reason for the position-momentum uncertainty

principle

am i right with this?

thanks
