Physics - Wave on String Question with Solution | TestHub

Two wires$W_1$and$W_2$have the same radius$r$and respective, densities${\rho }_1$and${\rho }_2$, such that${\rho }_2=4{\rho }_1$. They are joined together at the point$O$, as shown in the figure. The combination is used as a sonometer wire and kept under tension$T$. The point$O$is midway between the two bridges. When a stationary wave is set up in the composite wire, the joint is found to be a node. The ratio of the number of antinodes formed in$W_1$to$W_2$is
