The second harmonic frequency on a stretched wire, with a tension of 50 N and a mass per unit length density of 0.025 kg m-1, is measured to be 200 Hz. What is the length of the wire?

2. Relevant equations

L=λ/2

3. The attempt at a solution

As far as i've discovered i must find L, but i am not sure if this is the correct formula:

L=λ/2

In case it is correct, then what is the relation between mass, frequency,tension and length.

If it is not, then what formula i should use in order to get length?

I searched throughout google, but i couldn't find any other formulas. Totally confused:/
