The Probability Wave:
The Wave Function:
This is an animation of the Finite Step problem, as described in a typical undergraduate quantum mechanics textbook.
- The top animation shows the evolution of the probability density function.
- The bottom animation shows the full wave function . The real part is blue and the imaginary part is red.
- Note how the probability wave “tunnels” a little way through the potential barrier.
Note: The animation may look better if you view it directly on Vimeo. Just click on the word “Vimeo” on the player.
