Homework Statement
An electron in a one-dimensional box with walls at x =(o,a) is in the quantum state
psi = A o<x<a/2
psi = -A a/2<x<a
A) obtain an expression for the normalization constant, A.
B) What is the lowest energy of the electron that will be measured in this state?
Homework Equations
Not given anything. But its a chapter on Hermitian operators, and Hamiltonian.
The Attempt at a Solution
So for part a I think I am just supposed to normalize, so 1=integral of A*A ... and I get A=(a)^(-1/2) which i think is my normalization constant.
But is it asking not for the constant but to work back and find an equation?
For part b,,, I just operated on psi with the Hamiltonian and because all I had were constants, I got zero... which is boring if true, but I think isn't the answer I am looking for.
If anyone could help out, many thanks.
