Instructions / Notes:

• Hold the square wave from side corner and gently twist, flick, and spin it to observe different waves.

• It can also be hung from a ring stand.
• Sinusoidal wave pattern can be seen in the center.
• The longer rods have more potential energy, and the short rods have more kinetic energy, causing them to move slower and faster respectively.
• Faculty: Request a ring stand and demo camera for it to be seen better by larger classes.
