Two interfering waves of the same frequency are in phase but have diff – InterviewSolution

1.	Two interfering waves of the same frequency are in phase but have different amplitudes A1 and A2 . What can you say about the intensity of the resultant wave ?
Answer» The two waves interfere in phase. Thus, the amplitude and hence the intensity of the resultant wave is maximum, I_max ∝ (A _min)² where (A _max)² = (A₁ + A₂ )² .
