The sound a string guitar can be varied by changing the tension in each string.
a) if the force doubles what will happen to the transverse wave speed?
b) if the linear mass density of a 10.0 m band is 0.125 kg/m and it is stretched by a force of 9.00 N what is the wave speed?
c) what are the wave's natural frequencies?
