Complete the following table for these simple quantum mechanical models. You don't need to memorize the equations but you should become familiar with them. Being familiar with these simple models will help as we build up more complicated models in module 8. Each model will require you to fill in and/or annotate 5 rows of the table according to the directions in bold under the "model" column.
