Homework Statement
A particle in an infinite box is in the first excited state (n=2). Obtain the expectation value 1/2<xp+px>
2. The attempt at a solution
Honestly, I don't even know where to begin.
I assumed V<0, V>L is V=∞ and 0<V<L is V=0
I tried setting up the expectation value formula
1/2∫x|ψ*Pψ|2+(x|ψ2)*P x|ψ|2
but what is ψ? is it √(2/L) Sin ((n2πx)/L) because its the solution to the infinite well? are the bounds from 0 to L?
Thanks for viewing my question!
