An aluminium wire of length 60 cm and cross sectional area10^(-2) cm^(2)is joined with a steel wire of the same cross sectional area. A 10 kg mass is used to produce tension in the conjoined wires. The length of the steel wire is 86.8 cm . A transverse wave is produced in the wire with the help of an external source . Find the minimum frequency of vibration in the wire for which a stationary wave is produced with a node formed at the junction of the two wires.The densities of aluminium and steel are 2.6 g*cm^(-3) and 7.8 g*cm^(-3), respectively .
