Then it is clear that, outside the interval x ∈ {\displaystyle x\in } , the potential energy density is smaller for the ψ' because | ψ ′ | < | ψ | {\displaystyle |\psi '|<|\psi |} there.
Maka jelas bahwa, di luar interval x ∈ {\displaystyle x\in } , kerapatan energi potensial lebih kecil untuk ψ' karena terdapat | ψ ′ | < | ψ | {\displaystyle |\psi '|<|\psi |} .
