Abstract

In the meantime I have succeeded in several further experiments. By means of the oscillations I used in my previous work I am now able to produce standing waves with many nodes in straight stretched wires. If I content myself with 4 to 5 nodes, I can make them almost as clearly visible as the nodes of a vibrating string. (Letter of December 8th, 1887; MLD 239, emphasis added).
