Waves from two different sources overlap a particular point. The amplitude and frequency of the two waves are same.The ratio of the intensity when the two waves arrive in phase to that when they arrive 90^(@) out of phase is : |

Answer» `1 : 1` `therefore I_(1) = 4a^(2)` When phase difference is `90^(@)`, resultant amplitude ` = [a^(2) + a^(2)]^(1/2) = sqrt 2a` `therefore I_(2) = 2a^(2)` `RIGHTARROW (I_(1))/(I_(2)) = (4a^(2))/(2a^(2)) = 2/1` |
