Given a wave of a particular wavelength and amplitude, what must be the amplitude, wavelength, and phase change of a wave you add to this wave to create a wave of twice the amplitude? The added wave must have the same amplitude, the same wavelength, and a phase difference of 180 degrees with respect to the original wave. The added wave must have the same amplitude, the same wavelength, and a phase difference of 0 degrees with respect to the original wave. The added wave must have twice the amplitude, twice the wavelength, and a phase difference of 0 degrees with respect to the original wave. The added wave must have twice the amplitude, the same wavelength, and a phase difference of 180 degrees with respect to the original wave. The added wave must have the same amplitude, twice the wavelength, and a phase difference of 0 degrees with respect to the original wave
