At x = L, ψ ( L ) = 0 = C sin ⁡ k L . {\displaystyle \psi (L)=0=C\sin kL.\!} in which C cannot be zero as this would conflict with the Born interpretation.
Pada x = L, ψ ( L ) = 0 = C sin ⁡ k L . {\displaystyle \psi (L)=0=C\sin kL.\!} dimana C tidak boleh nol karena akan konflik dengan interpretasi Born.
