uncertainty relation.




I think I'm on the right track.

Currently, I'm at,

E = (1/2m)*<p^2> + (1/2)*k*<x^2>

and when applying the uncertainty relation,

deltax = <x^2>^(1/2)

deltap = <p^2>^(1/2)

How do I go about connecting everything from here?

Thanks!

You want to use the fact that the oscillator is in the ground state. Looking at the ground state wave function, can you get at estimate for either uncertainty?
