I have to calculate the Expectation Value of an Energy Eigenstate : < En >
The integral is ∫ ψ* En ψ dx
I have :
A ) ψ = √L/2 sin nπx/L , a single standing wave of the wave function
B ) ψ = BsinBcosD , the wave function of the particle
C ) ψ = ΣCn ψn = C , sum of all the standing waves
Which ψ do I use ? Why ? What's wrong with using the other two ?
