Frequency of the mains

This simple investigation can be linked to standing waves and builds on work done at GCSE.  In it students look at sending a current through a wire, suspended in a magnet which causes it to oscillate.  From this they can work out the frequency of the mains supply.  They can alter wire length and tension to see if this impacts their results.
