15.61: ω k F v F F μ F μF = = = a) and substituting this into Eq. (15.33) gives the result. b) Quadrupling the tension for F to F F 4 = increases the speed μ F v = by a factor of 2, so the new frequency ω and new wave number k are related to . k ω k ω k ω ) ( 2 ) ( by and = For the average power to be the same, we must have 4 and 4 so , ω k ω k ω k F Fkω
