Question

2) Two long wires of different composition are joined together at the origin (z-0) and held under a tension of T= 110 N. The mass densities of the left and right wires are μ-88/m and μ2 =52 g/m respectively. A traveling sinusoidal wave of amplitude Al-2 mm and frequency 200 Hz is incident on the boundary from the left (traveling towards the right). Calculate the following quantities, and retain at least 6 signif- icant figures in all values to reduce round-off error: a) the wave velocities vi and v2, in m/s, b) the wavelengths λ1 and λ2, in m, c) the amplitudes AR and AT of the reflected and transmitted waves, in mm d) State whether or not the reflected and transmitted waves are inverted relative to the incident wave.
