Slinky Waves Two Ways

The slinky carries transverse and longitudinal waves.

Teaching & key ideas

What you do: Show side-to-side and push-pull pulses. What students see: The slinky carries transverse and longitudinal waves. Why it works: Waves transfer energy while the material mostly oscillates in place. Question to ask: Does the slinky itself travel down the room?
