The string fixed at both ends has infinitely many normal modes because it is made up of a very large (effectively infinite) number of particles. If we could displace a string so that its shape is the same as one of the normal-mode patterns and then release it, it would vibrate with the frequency of that mode. Vibration Modes of a String: Standing Waves 11.1 Objectives • Observe resonant vibration modes on a string, i.e. the conditions for the creation of standing wave patterns. • Determine how resonant frequencies are related to the number of nodes, tension of the string, length of the string, and density of the string. • Determine the velocity, c, of transverse waves in the string. 11.2
