Consider a guitar string stretching 85.6 cm between its anchored ends.
The string is tuned to play middle C, with a frequency of 256 Hz, when oscillating in its fundamental mode, that is, with one antinode between the ends.
If the string is displaced 1.90 mm at its midpoint and released to produce this note, what are the wave speed, v, and the maximum speed, Vmax, of the midpoint of the string?
