    1. The problem statement, all variables and given/known data
    An electron in a very thin wire of length L= 1 nm (10-9 m) can be modeled as a particle in an infinite box.
    Solve for total energy using boundary conditions at L

    2. The attempt at a solution
    WaveFunction -- > PSI = A Sin ( kx ) ;
    k = n*pi/L ; A = sqrt(2/L) "After normalizing"
    Boundary condition at L -- > PSI(L) = 0
    now can I solve for E using this equation ?
    n*pi/L = k = sqrt( 2m*E/h^2)

    Welcome to pf.
    if in doubt, solve the schrodinger equation.
