Physics - Wave Optics Question with Solution | TestHub

$S_1, S_2$are two coherent sources (having initial phase difference zero) of sound located along$x$−axis separated by$4\lambda$where$\lambda$is wavelength of sound emitted by them. Number of maxima located on the elliptical boundary around it will be : [$S_1$and$S_2$are assumed to be at focus of ellipse]
