1 A guitar string of length 80cm is tuned to the musical note A which has a (fundamental) frequency of 220Hz. a) Calculate the speed of the wave along the guitar string Do now:Hātarei, 10 Whiringa-ā-nuku 2015 A different note is then played by placing your finger half-way along the string. b)Calculate the frequency of the new note

2 Halving the length produces a wave of twice the frequency – this is one octave
