A demonstration machine for cross and longitudinal waves. Very useful in monitoring and surveying the wave of its length, frequency, amplitude and period.
The machine consists of a shaft with a knee at the end. The rotation of the shaft drives the sticks. Through the 8 sticks bent at the same angle, the two types of waves are observed.
