Two waves with identical frequency but different amplitudes A1 = 6.0 cm and A2 = 3.0 cm, occupy the same region of space (i.e., are superimposed).
(a) At what phase difference will the resulting wave have the highest intensity? What is the amplitude of the resulting wave in that case?
(b) At what phase difference will the resulting wave have the lowest intensity and what will its amplitude be?
(c) What is the ratio of the two intensities?
