Quantum note
A wave packet arrives from the left and hits the potential barrier → part reflects, part tunnels through even though E<V₀ · adjust E · V₀ · width a on the right

About Quantum Tunneling

Quantum Tunneling is one of 20 topics in the Particle & Quantum domain (10⁻¹⁵ m scale) at My Labs — an interactive simulation atlas. This virtual lab runs right in your browser: adjust the parameters, pick a scenario and watch the phenomenon change in real time, with a click-to-inspect cross-section for every structure.
