A wire is stretched with tension T. A transverse wave traveling
on this wire with amplitude A and wavelength λ1 carries an average
power Pav,1 = 0.400 W. If the wavelength of the waves is doubled,
and a second wave is created so λ2 = 2λ1, while the tension T and
amplitude A are not altered, what then is the average power Pav,2
carried by the second wave? Express your answer in both general
terms (i.e. in terms of the variables given in the problem) as well
as numerically (i.e. plug in the value given).
