A long string of mass per unit length $0.5\, {\rm kg\, m}^{-1}$ is stretched to a tension of 100 N. Find the speed of transverse waves on the string and the mean power required to maintain a traveling wave of amplitude 15 mm and wavelength 0.25 m.
The string is joined to another of mass per unit length $0.8\, {\rm kg\, m}^{-1}$. What fraction of the power carried by the wave is transmitted to the second string?
