Note that the kinetic-energy density | d ψ ′ d x | 2 < | d ψ d x | 2 {\displaystyle \left|{\frac {d\psi '}{dx}}\right|^{2}<\left|{\frac {d\psi }{dx}}\right|^{2}} everywhere because of the normalization.
Perhatikan bahwa kerapatan energi kinetik | d ψ ′ d x | 2 < | d ψ d x | 2 {\displaystyle \left|{\frac {d\psi '}{dx}}\right|^{2}<\left|{\frac {d\psi }{dx}}\right|^{2}} di mana-mana karena normalisasi.
