Two identical guitar strings are prepared such that they have the same length (2.04 m) and are under the same amount of tension. The first string is plucked at one location, primarily exciting the 2nd harmonic. The other string is plucked in a different location, primarily exciting the 3rd harmonic. The resulting sounds give rise to a beat frequency of 387 Hz. What is the wave propagation speed on the guitar strings?
