Aspeaker is located at r1 .3,-2.1)m and another speaker is located at r2-(2.5,-2.8)m. the two speakers emit waves so that they have the same amplitude at the point where they are being observed if the frequency of sound emitted is 238 hz and the observation point is ro-(1.0,2.4), what is the ratio of the intensity of the sound at point ro relative to the maximum possible intensity if the waves didn't interfere, io? (take the speed of sound to be 343 m/s.)
