# Transmission and Reflection Coefficients of Quantum Particles

Transmission and Reflection Coefficients of Quantum Particles

This Demonstration shows the transmission coefficient and the reflection coefficient of a quantum particle with energy hitting a rectangular potential barrier. See how the height of the potential barrier affects and by comparing the cases and . The dimensionless coordinate is the product of the wavenumber for the wave inside the barrier and the barrier width .
