The Potential Barrier, case E ≤ V₀ - Tunneling
We seek to answer a key question What happens inside the potential barrier when the energy is less than the potential V. In classical mechanics, the particle cannot exist in this region. In quantum mechanics, it can. Employing mathematics, we explain what happens as attributed to the wave-like behavior of the particle.
Note Unlike the previous problems, I hope you watch all of the first four of this series, QM5.1 to QM5.4, to fully understand this phenomena.
