	/// The high E string on a guitar measures 64.0 cm in length
	/// and has a fundamental frequency of 330 Hz. By pressing down
	/// so that the string is in contact with the first fret, the
	/// string is shortened so that it plays an F note that has
	/// a frequency of 350 Hz. How far is the fret from the neck
	/// end of the string?
	/// 3.7 cm
