Physics - Sound Wave Question with Solution | TestHub

A source is moving on a circle of radius$3\mathrm{ }\mathrm{m}$with constant angular velocity$\mathrm{\omega }=5\mathrm{ }\mathrm{r}\mathrm{a}\mathrm{d} {\mathrm{s}}^{-1}$. If the observer is at a distance$5 \mathrm{m}$from the centre of the circle, the time interval between the maximum and minimum frequency received by the observer is
