Calculate the fundamental frequency of a sonometer wire fo length 20cm, tension 25N, cross sectional area `10^(-2)cm^(2)` and density of material `=10^(4)kg//m^(3)`.

Explanation

To calculate the fundamental frequency of a sonometer wire, we can use the formula for the fundamental frequency \( f_1 \):

\[ f_1 = \frac{1}{2L} \sqrt{\frac{T}{\mu}} \]

where:
- \( L \) = length of the wire
