Chapter 2: Q24E (page 498)
A light wire is tightly stretched with tension F. Transverse traveling waves of amplitude A and wavelength A₁carry average power Pavg = 0.400 W. If the wavelength of the waves is doubled, so A₂= 2A₁, while the tension F and amplitude A are not altered, what then is the average power Pav,2 carried by the waves?
Short Answer
The average power carried by the waves is .
