Suppose a particle has zero potential energy for x < 0, a constant value V, for 0 ≤ x ≤ L, and then zero for x > L. Sketch the potential. Now suppose that wavefunction is a sine wave on the left of the barrier, declines exponentially inside the barrier, and then becomes a sine wave on the right, being continuous everywhere. Sketch the wavefunction on your sketch of the potential energy.
