Will it be possible to monitor the temperature of the wire by measuring its vibrational frequency?



Cause of vibration not mentioned but one thing is certain that frequency of vibration is dependent on length of wire.
So frequency(n)=function of length (l) n=f(l)
again length l is dependent on temparature T l=g(T)
So co relating....n=f(g(T)) thus there is a co relation between
Frequency and temparature...
