Today: We talked about standing waves (from 9.2), and used the guitar as an example.
The video for 9.2 is online, but many students were still catching up on 8.1-9.1.
The Unit 4 Test (Chapters 8-9) will be on Wed. May 20.
See the Lessons page for all handouts and videos.
Homework: Catch up on videos - do as many as you can at home!
