Quantum Tunneling

Explore how quantum particles tunnel through potential barriers. Adjust energy, barrier width, and particle mass to see how tunneling probability changes. Compare quantum predictions with classical physics.

Wave Representation
Classical prediction: 0% transmission (impossible)
Quantum result: Depends on parameters
