← ScienceWhich consequence results when a quantum mechanical wave function representing a particle encounters a potential energy barrier?
A)Reflection increases proportionally with barrier height
B)Diffraction pattern shifts towards higher momentum
C)Tunneling probability decreases exponentially with width✓
D)Wave function constructively interferes within barrier
💡 Explanation
When a wave function encounters a potential barrier, quantum tunneling may occur because the wave function has a non-zero probability of penetrating and appearing on the other side. Therefore, tunneling probability decreases exponentially with increased barrier width, rather than other options which relate to different quantum phenomena.
