A long wire PQR is made by joining two wires PQ and QR of equal radii PQ has length 4.8 m and mass 0.06 kg . QR has length 2.56m and mass 0.2 kg . The wire PQR is under a tension of 80N . A sinusoidal wave-pulse of amplitude 3.5cm is sent along the wire PQ from end P . No power is dissipated during the propagation of the wave-pulse. caculate, (a) the time taken by the wave-pulse to reach the other end R of the wire, and (b) the amplitude of the reflected and transmitted wave-pulse after the incident wave-pulse crosses the jjoint Q .

A Uniform rope having mass m hags vertically from a rigid support. A transverse wave pulse is produced at the lower end. The speed v of wave pulse varies with height h from the lower end as

A uniform rope having some mass hinges vertically from a rigied support. A transverse wave pulse is produced at the lower end. The speed (v) of the wave pulse varies with height (h) from the lower end as :-

A string is hanging from a rigid support. A transverse wave pulse is set up at the bottom. The velocity v of thr pulse related to the distance covered by it is given as

A heavy rope is suspended from a rigid support A wave pulse is set up at the lower end, then
