Speaker $1$ is located at $($x$,$y$)=(0,3)$ m and speaker $2$ is at $($x$,$y$)=(0,0)$ m$.$ They play the same frequency sound in the same phase. What is the minimum frequency in hertz that would result in constructive interference$$ at the point $($x$,$y$)=(5,0)$ m$?$ Speed of sound: $344$ m$/$s$.$
