A sonometer wire of fixed length and mass per unit length is tensioned to a value TTT. The fundamental frequency of the stationary wave formed on this wire is fff.
The tension in the wire is now increased to 4T 4T\,4T without changing its length or mass.
Which harmonic of the wire has a frequency of 10f 10f\,10f after this increase in tension?
