W.2.7 Fluorescent Motor Driven String This demo illustrates the normal modes in standing waves. A black light shines on a motor- driven fluorescent string. As the input frequency changes and corresponds to one of the normal modes or harmonics, the nodes and antinodes appear. A strobe may be used to "freeze" a particular harmonic. |
