A sonometer wire is in unison with a tuning fork of frequency ' $n$ ' when it is stretched by a weight of specific gravity ' $d$ '. When the weight is completely immersed in water, ' $x$ ' beats are produced per second, then

$\frac{\mathrm{n}}{\mathrm{n}-\mathrm{x}}=\frac{\mathrm{d}}{\mathrm{d}-1}$

$\frac{n}{n-x}=\sqrt{\frac{d}{d-1}}$

$\frac{\mathrm{n}-\mathrm{x}}{\mathrm{n}}=\frac{\mathrm{d}-1}{\mathrm{~d}}$

$\frac{\mathrm{n}-\mathrm{x}}{\mathrm{n}}=\sqrt{\frac{\mathrm{d}}{\mathrm{d}-1}}$
