Physics - Sound Wave Question with Solution | TestHub

Two sonometer wires $\mathrm{A}$ and $\mathrm{B}$ are fixed on a sonometer. The ratio of their lengths, diameters, densities and tensions are given below:

$\frac{{\mathrm{l}}_{\mathrm{A}}}{{\mathrm{l}}_{\mathrm{B}}}=\frac{36}{35}$;     $\frac{{\mathrm{d}}_{\mathrm{A}}}{{\mathrm{d}}_{\mathrm{B}}}=\frac{4}{1}$;     $\frac{{\mathrm{T}}_{\mathrm{A}}}{{\mathrm{T}}_{\mathrm{B}}}=\frac{8}{1}$;     $\frac{{\mathrm{\rho }}_{\mathrm{A}}}{{\mathrm{\rho }}_{\mathrm{B}}}=\frac{1}{2}$

If the higher frequency among the two wires is $360 \mathrm{Hz}$, then what is the beat frequency (in $\mathrm{Hz}$) observed when the two wires are sounded together?
