21M.2.HL.TZ1.8c

On a guitar, the strings played vibrate between two fixed points. The frequency of vibration is modified by changing the string length using a finger. The different strings have different wave speeds. When a string is plucked, a standing wave forms between the bridge and the finger.

                                                       

(c)

The string is made to vibrate in its third harmonic. State the distance between consecutive nodes.
