PhysCasts: The Length of a Vibrating Spring

Rowlands, W. (Wayne)


This PhysCast is going to look at standing waves on a stretched string. A 45 gram string is tightly stretched and fixed firmly at each end. The tension in the string is 78 N, and it vibrates with its 3rd harmonic at 120 Hz. How long is the string?
