Part 1
1. Lay a slinky (from your science kit) on a table and hold both ends. Stretch the slinky across the length
of the table and push the slinky towards the right with your left hand.

a. What type of wave was created? How do you know? (2pts)

2. Take the same slinky, hold both ends, and whip the left end up and down while you hold the right end
steady.
