- Simultaneously presenting tones of the same frequency and amplitude from two different sound sources will A always result in a doubling of the amplitude of the sound reaching the listener. B result in a doubling of the sound amplitude reaching the listener only if the sources are 180-degrees out of phase. C result in a doubling of the sound amplitude reaching the listener only if the sources are 90 degrees out of phase. D result in a doubling of the sound amplitude reaching the listener only if the sources are in phase.Two identical waves travel in the same direction on a string. And Interference occurred If the amplitude of each wave is 10.0 mm and has a phase difference of 120 degrees, find the amplitude of the resulting wave (in mm)
