Two identical strings are each under the same tension. Each string has a sinusoidal wave with the same average power Pav. If the wave on string #2 has twice the amplitude of the wave on string #1, the wavelength of the wave on string #2 must be O half of the wavelength of the wave on string #1. O four times the wavelength of the wave on string #1. the same as the wavelength of the wave on string #1. O one-quarter of the wavelength of the wave on string #1. O twice the wavelength of the wave on string #1
