The GG 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 frets, which changes the string's length. The ninth fret
from the neck gives EE (329.63 Hz); the tenth
fret gives FF (349.23 Hz).
How far apart are the ninth and tenth frets?
