A wire is made by welding two wires (radii r and 2r) at one of its ends. This combined wire is used in the sonometer, under tension T with the welding point just in middle of the bridges. On vibrating, stationary waves are produced. If welding point is a node, then the ratio of loops formed in both the parts will be
