Particle in a Box - Electricity, Magnetism, Optics and Quantum Mechanics - Fundamentals of Physics - Ramamurti Shankar - Lecture 23 of 25 - Video-lecture

Video-lecture, Advanced Physics

Description: The allowed energy states of a free particle on a ring and a particle in a box are revisited. A scattering problem is studied to expose more quantum wonders: a particle can tunnel into the classically forbidden regions where kinetic energy is negative and a particle incident on a barrier with enough kinetic energy to go over it has a nonzero probability to bounce back.
