Explanation:
Givens
The frequency is defined by
Where is the speed of the wave in the string and
is its wave length.
The wave length is defined as
Now, to find the speed, we need the tension of the wire and its linear mass density
Where and the tension is defined as
Replacing this value, the speed is
Then, we replace the speed and the wave length in the first equation
Therefore, the frequency is
