Statement of a problem № 42408


A sinusoidal transverse wave travels on a string. The string has length 8.00 m and mass 6.00 g. The wave speed is 30.0 m/s, and the wavelength is 0.200 m. (a) IT the wave is to have an average power of 50.0 W, what must be the amplitude of the wave? (b) For this same string, if the amplitude and wave length are the same as in part (a), what is the average power for the wave if the tension is increased such that the wave speed is doubled?
