Demo Title: Hanging Slinky
Condition: Excellent
Principle: Longitudinal Waves
Area of Study: Oscillations & Acoustics
Equipment:
Hanging Slinky Apparatus
Procedure:
Move the masses on the end exciters to give the desired frequency. Start the exciters and observe the longitudinal waves travel down the slinky.
