14. You want to calculate electron waves 4(x) in a thin wire (1-dimensional). What if the potential outside the wire were infinite? Which of the following statements are correct in this scenario?

(A) The allowed kinetic energies of electrons should be quantized.
(B)ψ(x)≈ 0 everywhere000 eV
(C) ψ(x) ≈0 everywhere, except for 0＜x＜L. 이 L
(D)ψ(x) = 0 everywhere, except for 0＜x＜L
(E) Can't tell anything yet. Need to find ψ(x) first.
