Student Manual | ![]() The experiment gives you an introduction to the phenomenon of resonance, and the frequencies at which it occurs by visualizing the stationary waves formed on a vibrating string. We will learn the effect of change in tension and string length on resonance. We shall also investigate the non linearities in a vibrating string. Experiment also provides an introduction to another very interesting phenomenon of formation of circular modes on a string. |
