Two waves with identical frequency but different amplitudes A 1 = 5.0 cm and A 2 = 3.0 cm, occupy the same region of space (are superimposed).
(a) At what phase difference does the resulting wave have the largest amplitude? What is the amplitude of the resulting wave in that case?
(b) At what phase difference does the resulting wave have the smallest amplitude and what is its amplitude?
(c) What is the ratio of the largest and smallest amplitudes?
