A student plays a guitar and notices that altering the tension in one of the strings alters the frequency of the note played. The student thinks that this happens because the speed of the wave has changed. 1 Plan an investigation which will determine if the speed of the wave in a wire is related to the tension (stretching force) in that wire.
Your plan should include: • an equipment list • a risk assessment • a method • a table for results.
