Two interfering waves of the same frequency are out of phase but have different amplitudes A1 and A2 . What can you say about the intensity of the resultant wave ? |

Answer» The two interfering waves are out of phase. Thus, the amplitude and hence the intensity of the resultant wave is minimum, Imin ∝ (A min)2 where (A min)2 = (A1 – A2 )2 . |
