Description: This demonstration uses metal rods to show properties of standing waves.
Procedures: Hold the rod in the middle in one hand, and with the other hand already covered in rosin powder, grab one end and slide your finger along the rod using a fair amount of grip force. Some rods are also marked at fractions of the fundamental frequency. Some points do not allow for standing waves, while other allow for only specific frequencies.
Note: Using the rosin powder is highly recommended.
