# Sonometer experiment.

Classical Mechanics Level pending

A sonometer wire resonates with a given tuning fork forming standing waves with three antinodes between the two bridges when mass $$M$$ is suspended from the wire. When this mass is completely immersed in a liquid of density $$\rho_l$$, the wire resonates with same tuning fork forming five antinodes for the same position of the bridges. The ratio of density of liquid and density of mass $$M$$, $$\frac{\rho_l}{\rho_m}$$, is :
