Two waves with identical frequency but different amplitudes, Ask an Expert

Academics

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) What is the amplitude of the resulting wave if they interfere constructively?

(b) What is its amplitude if they interfere destructively?

(c) By what factor is the intensity larger for constructive interference than the intensity for destructive interference?
