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)

Additional programs

Franck-Hertz Experiment (Windows, Mac)

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.

Hydrogen Spectroscopy (Windows only)

Zeeman Effect Experiment (Windows only)

Semiconductor Device Simulator (Windows only)

Two error messages will appear when the program starts. Click OK for each and the program seems to run fine.
