Shrodinger equation/Particle in a box

  • #1
1. What is U(x)psin(x) in the interval 0 < x < L? (less than or equal to)



2. In previous problems I had found the following:

Second deriv. of psi(x) = -(n*pi/L)2*C*sin(n*pi*x/L)

U(x)*psin(x) = 0





3. From the above and the Shrodinger equation, I added U(x) = 0 to the second derivative of psi given above multiplied by -h-bar/2m, obtaining the incorrect answer of:

(h-bar*n*pi)2/2mL2 * C * sin(n*pi*x/L)

I don't think you will receive much help if you don't clearly explain your problem. For example, what is U(x)? Also, you might want to use latex or people will be put off trying to decipher what you wrote.
