The G string on a guitar is 59 cm long and has a fundamental frequency of 196 Hz. A guitarist can play different notes by pushing the string against various trets, which changes the string's length. The fifth fret from the neck gives C (261.63 Hz) the sich fret gives Db (277.18 Hz). Part A How far apart are the fifth and sixth frets? Express your answer to two significant figures and include the appropriate units. HA ? AL =...
