The top string of a guitar has a fundamental frequency of 300 Hz when it is allowed to vibrate as a whole, along all its 60.0 cm length from the neck to the bridge. A fret is provided for limiting vibration to just the lower two-thirds of the string. The guitarist can play a "natural harmonic" by gently touching the string at this fret and plucking the string at about one sixth of its length from the bridge. What frequency will be heard then?

300x3 = 900 Hz
