The source $S_1$ is located at $O$ and $S_2$ moves anti$-$clockwise with a uniform speed $4 \sqrt{2} \ ms ^{-1}$ on a circular path around $O$, as shown in the figure. There are three points $P, Q$ and $R$ on this path such that $P$ and $R$ are diametrically opposite while $Q$ is equidistant from them. A sound detector is placed at point $P$. The source $S_1$ can move along direction $O P.[$Given: The speed of sound in air is $324 \ ms ^{-1} ]$View Solution
$(1)$ When only $S_2$ is emitting sound and it is $Q$, the frequency of sound measured by the detector in $Hz$ is $. . . . .$
$(2)$ Consider both sources emitting sound. When $S_2$ is at $R$ and $S_1$ approaches the detector with a speed $4 \ ms ^{-1}$, the beat frequency measured by the detector is $Hz$.
