When one plucks a violin, or guitar, string, the string vibrates ex-hibiting a variety of sounds. These are enhanced by the violin case, but we will only focus on the simpler vibrations of the string. We will consider the one dimensional wave motion in the string. Physically, the speed of these waves depends on the tension in the string and its
A particular quantum vibration mode of the closed string describes a graviton, the quantum of the gravitational field. A particular quantum vibration of an open string describes a photon, the quantum of the electromagnetic field. It is the magic of quan-tization that makes these results possible.
Transverse vibration of a taut string Referring to Figure 1, consider a taut string stretched between two fixed points at x =0 and x = L. Let the cross-sectional area be S. If there is an initial stretching of ∆L,the initial tension T must be ∆L T = ES L by Hooke’s law, where E is Young’s modulus.

A vibration in a string is a wave. Resonance causes a vibrating string to produce a sound with constant frequency, i.e. constant pitch. If the length or tension of the string is correctly adjusted, the sound produced is a musical tone.
zero, record the value including sign, 2) add the string and record the string mass [don’t forget to correct for the zero reading if it wasn’t zero], 3) remove the string and verify that the zero
17.9: Vibrating String. Page ID. Jeremy Tatum. University of Victoria. It is possible that the three modes of vibration of the three masses in Section 17.8 reminded you of the fundamental and first two harmonic vibrations of a stretched string – and it is quite proper that it did.
