Purpose: Demonstrate standing waves in a stretched wire and to demonstrate Mersenne's first and second laws.
Description: The tensions in two stretched wires can be separately adjusted, creating different fundamental frequencies. Stops can be inserted along the wire to observe the frequency as a function of length, or to show the frequency ratio between two similar wires with the same tension but of different lengths. Note: this is easier to use than the sonometer with weights, but the tension cannot be measured quantitatively.
