The fundamental frequency of a sonometer wire is $n$ . if the length and diameter of the wire are doubled keeping the tension same, then the new fundamental frequency is

Options:

Answer:

Solution:

The fundamental frequency of a sonometer wire is

$f = \frac{1}{2 l} \sqrt{\frac{4 T}{π ρ d^{2}}}$

$\Rightarrow f \propto \frac{1}{l d}$

So if the length and diameter of the wire are doubled, then its frequency becomes one-fourth
