Gaussian Wavepacket Incident on a Potential Step

Gaussian Wavepacket Incident on a Potential Step

This animation shows the spreading of a Gaussian wave packet describing a free quantum particle, and allows the user to change the initial width of the wave packet to see how this influences the spreading time. A "step-by-step exploration" tab explains the key points. The animation can be downloaded. Instructors can email ak81@st-andrews.ac.uk for the password for the instructor resources.
