Physics - Sound Wave Question with Solution | TestHub

$S_1$ and $S_2$ are two stationary sources separated by a distance of 2 m from each other producing sound at 1440 Hz in same phase. A detector D is moving in a circle of radius 10 m around O (mid-point of line joining $S_1$ and $S_2$). If in one complete revolution it detects maximum intensity $x/3$ times, then x is :- (Speed of sound $=360\mathrm{m}/\mathrm{s}$) (O is center of circle)
