Some Unique Issues of Individual Student
Preparation for this course
Prereqs Physics 212 OR Physics 221
More than Half of you have taken 211, 212, AND
221 (some even have taken 232 Waves)
Some of you took Physics 212 quite some time ago.
There will be some issues with Unit I
Oscillations and Waves.
