Homework Statement
[/B]
For the first excited state of a Q.H.O., what is the probability of finding the particle in -0.2 < x < 0.2
Homework Equations
Wavefunction for first excited state: Ψ= (√2) y e-y2/2
where:
The Attempt at a Solution
To find the probability, I tried the integral of : |Ψ|2
but this gives the integral of gaussian. From what I've read, the integral of a gaussian can only be solved from -infinity to infinity. So how can I find it from -0.2 to 0.2?
