Slinkies  and Interference

If you missed today:

1. We collect Great America $ ($32 by this Friday down payment and $30 after that to pay the total)

2.  I filled out the top half of the interference homework sheet and assigned students the bottom half for 6 points (due tomorrow but most turned it in today).

3.  Explained the Slinky Lab and sent students out in pairs to complete the lab and turn in before they left.  Get someone who did the lab to come up and get the lab done with you.  No summary or conclusion is necessary, just answer the questions (showing calculations for number 5) and draw the two diagrams for transverse and longitudinal waves with vocabulary (found on the bottom of this vocabulary sheet).
