Hi--could someone explain how can one calculate for the root mean square fluctation in position when an electron (confined in a box) is quantum-mechanical and happens to be in a state (an infinitely large quantum number n) and why?(adsbygoogle = window.adsbygoogle || []).push({});

I do know how to calculate root mean square fluctation in position with the given function and n, as in (root-mean)^{2}= <x^{2}> - <x>^{2}but am not sure how to do this with huge n value. Do I just use Schrodinger equation, where V (potential) is equal to 0?
