Two pieces of steel wire with identical cross sections havelengths of L and 3L.Each of the wires is fixed at both ends and stretched so that thetension in the longer wire is fourtimes greater than that in the shorter wire. If the fundamentalfrequency in the shorter wire is 50Hz, what is the frequency of the second harmonic in the longerwire?
There is already a similar question on this one. However, theproposed solution help wasn't much help. Will you please make theconnection of what values are to be plugged in? Thanks.
