Quantum Motion,used in Waves of Matter Unit 10, is no longer available. A suitable substitute is for a simple wave packet spreading is Time Development of a Wave Packet (QuVIS). To have students set up other situations involving time evolution of wave packets we recommend Quantum Tunneling and Wave Packets (PhET)
ERROR WARNING: For neon, the grid voltages are too low by a factor of 10. When working with neon, multiply the values of VG by 10 in all 3 places that it appears.
