Two strings A and B have lengths lA ​and lB ​ carry masses MA and MB at their lower ends the upper ends being supported by rigid supports. If nA and nB are the fundamental frequencies of their vibration, then nA : nB is

A stationary wave set up on a string have the equation y = (2mm) sin [(6.25 m^-1) x cos (ωt)]. This stationary wave is created by two identical waves of amplitude A each moving in opposite directions along the string. Then
