Question: Three similar wires of frequency $n_1$, $n_2$ and $n_3$ are joined to make one wire. Its frequency will be

1) $n={{n}_{1}}+{{n}_{2}}+{{n}_{3}}$

2) $\frac{1}{n}=\frac{1}{{{n}_{1}}}+\frac{1}{{{n}_{2}}}+\frac{1}{{{n}_{3}}}$

3) $\frac{1}{\sqrt{n}}=\frac{1}{\sqrt{{{n}_{1}}}}+\frac{1}{\sqrt{{{n}_{2}}}}+\frac{1}{\sqrt{{{n}_{3}}}}$

4) $\frac{1}{{{n}^{1}}}=\frac{1}{n_{1}^{2}}+\frac{1}{n_{2}^{2}}+\frac{1}{n_{3}^{2}}$
